FORMULAS FOR SHAPES

About the topic formulas for shapes

In this page formulas for shapes you can find many shapes and related formulas.Mensuration is one of the branches of mathematics.This means measurement.It is is being done in our life in many situations.
For example,

A length of cloth we need for stitching, the area of a wall which is being painted, perimeter of the circular garden to be fenced. For these kind of situation we need to use one of these formulas. Here, we cover two major areas.

1. Perimeter

2. Area

Name of shape	Formulas
Circle
	Area of circle = Π r ² Circumference of circle = 2 Π r Example problems of area of circle Example problems of circumference of circle
Equilateral Triangle
	Area of Equilateral-triangle = (√3/4) a² Perimeter of Equilateral-triangle = 3a Example problems on equilateral triangle
Scalene Triangle
	Area of scalene triangle = √s(s-a)(s-b)(s-c) Perimeter of scalene triangle = a + b + c Example problems on scalene triangle

Formulas for shapes would be very useful for school students who are studying lower classes. Here you can find formulas almost for all the shapes. We have also given sample problems to understand these formulas. Most of the problems in mensuration can not be done without these formulas.We have explained each topic with clear pictures. Please go through the examples to understand this topic more clearly.
