Question

a length of a rectangle is 20 m and its breadth is 15 M how much distance will be covered in going around it once​

Answer 1

Distance covered by it = Area of rectangle


Area of rectangle = l×b


=> 20×15

=> 300m²

Answer 2

$\textbf{\underline{\underline{Answer :-}}}$

The distance covered by going around the Rectangle is 70 m

$\textbf{\underline{\underline{Explanation :-}}}$

Given :

The Length of the Rectangle = 20 m

Breadth of the Rectangle = 15 m

To find :

Distance covered by going around the Rectangle

Solution :

The distance covered by going around is actually the Perimeter of Rectangle.

So, to get the distance covered we need to find the Perimeter of Rectangle.

$\star$ Perimeter of Rectangle =

${\boxed{\sf \:{Perimeter = 2(Length + Breadth)}}}$

$\sf{\implies2(15 + 20)}$

$\sf{\implies30 + 40}$

$\sf{\implies70}$

${\boxed{\sf \:{Perimeter = 70 m}}}$

$\therefore$The distance covered by going around the Rectangle is 70 m
