The most important thing in **mathematics** is the formula. If you remember all the important formulas of maths then maths becomes very easy for you. So far we have read about different types of formulas in mathematics, similarly questions are asked on the formulas used in small classes in different types of competitive exams like SSC , UPSC , SSC CGL , JEE Mains etc. In our blog, we will give information about the formula of mathematics and will know which are the important formulas from the point of view of various competitive examinations, so let’s start with the formulas of mathematics-Table of contents

**What are math formulas called? **

Maths formulas are very important to solve maths questions, so in today’s blog we have covered all maths formulas.

As you all are well aware that a special method is required to solve the smallest problem in mathematics. can be done

“In **mathematics**, an equation formed using symbols and the rules of construction of a logic language is called a formula.”

In science, the representation of any information or mathematical relationship between different quantities in a small form is called a formula.

A chemical formula is also a way of symbolically summing up an element or compound.

For example, the following is the formula for the area of a circle – r2

**Maths Formulas: How many types of maths formulas are there? **

There are different types of maths formulas, from small classes to big classes, we have different types of maths formulas. In today’s blog we have provided you important formulas related to all classes which are as follows-

Algebra Formulas:

(a+b)² = a²+2ab+b²

(a-b)² = a²-2ab+b²

(a-b)² = (a+b)²-4ab

(a+b)² + (a-b)² = 2(a²+b²)

a³ + b³ = (a + b) (a²-ab + b²)

a³-b³ = (ab) (a² + ab + b²)

a³-b³ = (a-b)³ + 3ab(a-b)

(a²+1/a²) = (a-1/a)²+2

(a³+1/a³) = (a+1/a)³-3(a+1/a)

**All Formula of Mensuration**

Area of triangle – s(sa)(sb)(sc)

Types of Triangles and their Areas:

Isosceles Triangle: A triangle whose two sides are equal is called Isosceles Triangle.

isosceles triangle formula

Area of an isosceles triangle, A = a / 4 b √ (4b² – a²)

Vertex of an isosceles triangle = a / 4b √ (4b² – a²)

Perimeter, P = 2a + b

scalene triangle

**Scalene triangle A triangle whose three sides are of equal length. **

scalene triangle formula

Area of a polyhedron, A =√ [ s(s – a)(s – b)(s – c) ]

In other words, A = × base × height

Semiperimeter P = ( a + b + c )

right angled triangle

Area of a right triangle, A = × base × height

Perimeter of right angled isosceles triangle = (2 + 2) × side

Hypotenuse of right angled isosceles triangle = (√2) × side

Area of right angled isosceles triangle = × side2

equilateral triangle

**An equilateral triangle is a triangle whose all sides are equal.**

Area of Equilateral Triangle = (√3) / 4 × Side 2

altitude of an equilateral triangle = (√3)/4 × side

Perimeter = 3 × Side

**Rectangle : A rectangle is a quadrilateral whose opposite sides are equal and diagonals are also equal with each right angle (90º).**

Area of Rectangle – Length × Breadth

Perimeter of rectangle – 2 × (length + breadth)

Square: A quadrilateral is called a square, whose sides are equal and each angle is at right angles (90°).

Area of the square – side × side (a2)

Perimeter of square – 4 × side (4a)

Diagonal of Square – Side × 2

side – area

Area of Square – × Product of Diagonals

**Trapezoid : A quadrilateral in which only one pair of opposite sides is parallel is called a trapezoid.**

Trapezoid Formula

Area of trapezium = (sum of parallel sides x height)

= (base x corresponding height)

Perimeter, P = a + b + c + d

**Rhombus: A rhombus is a plane figure whose all four sides are equal.**

Formula of an equilateral quadrilateral

∠A + ∠B + ∠C + ∠D = 360°

Area of Rhombus = × Product of both the diagonals

In rhombus => (AC)² + (BD)² = 4a²

cyclic quadrilateral formula

∠A + ∠C = 180°

∠B + ∠D = 180°

Area = [s(sa) (sb) (s – c) (s – c)]

Perimeter, S = ( a + b + c + d )

**Polygon Formula**

Sum of interior angles of a quadrilateral of side n = 2(n –2) × 90°

Each end angle of an equilateral polygon = (n – 2) / 2 × 180

Each interior angle of a rhombus of side n = [2(n – 2) × 90°] / n

Perimeter of polygon = n × one side

Area of regular hexagon = 6 × 3 (side)²

Each exterior angle of a rhombus of side n = 360°/n

Area of regular hexagon = 3√3×½ (side)²

side of a regular hexagon = radius of the circumcircle

Number of diagonals of a regular polygon of n sides = n(n – 3)/2

circle formula

Area of the circle = πr²

diameter of circle = 2r

Circumference of circle = 2πr

circumference of circle = d

Radius of circle = area of √vrat /

Area of semicircle = 1/2πr²

Radius and Segment Formula

Area of a radius = θ / 360 ° × πr²

Length of arc = /360° × 2πr

Perimeter of a radius = 2r + πrθ / 180

Area of the arc = (πθ / 360 ° – 1/2 sinθ) r²

Perimeter of a segment = (L + πrθ) / 180 °, where L = length of chord

cube formula

Volume of cube = side × side × side = a3

Perimeter of a cube = 4 a²

One edge of the sidebar = √ (area of the sidebar / 4)

One side of the cube = 3√Volume

One side of the cube = (Area of the whole surface / 6 )

Area of the entire surface of the cube = 6a²

Diagonal of cube = 3 × side

Cuboid Formula

Volume of cuboid = l × b × h

Perimeter of cuboid = 2(l + b) × h

Total surface area of cuboid = 2(lb + bh + hl)

Diagonal of cuboid = (l² + b² + h²)

Height = Volume / (Length × Breadth) of the cuboid

Cuboid Width = Volume / (Length × Height)

Area of the four walls of the room = 2h ( l + b )

Area of lidless tank = 2h (l + b) + lb

Area of roof or floor = length × breadth
