Question

A rectangle has its area equal to that of a square of side $80cm.$ If the breadth of the rectangle is $20cm.$Find its length.

Answer 1

Find the length of the rectangle:

Here, the side of a square is $80cm.$

So, area of square =$80\times 80c{m}^2$

$=6400c{m}^2$

Since, Area of a rectangle is equal area of a square.

So, area of rectangle =$6400c{m}^2$

Here, breadth of rectangle =$20cm.$

So, length=$\frac{6400}{20}$

$=320cm.$

Hence, the length of the rectangle is $320cm$.
