Question

how to measure the area of rectangle,square,triangle and circle

Answer 1

Dear Student,

The Area of the following geometric figures can be find if the measure of the sides or radius is given.

1. Rectangle
if length L is given and Breadth B is given then area
$A=L\times B$
2. Square
As sides of square are equal, if are given the length of side S
Area $S\times S$

3. Triangle

if length of base and perpendicular of triangle is given then area of triangle
Area =$\frac{1}{2}\times b\times h$
in case all sides of a triangle are equal, then it is an equilateral triangle.
Area=$\frac{\sqrt{3}}{4}\times (side{)}^2$

4. Circle
if radius r is given of the circle.
Area=$\pi r^2$
