Question

The area of the rectangular lawn is 1800 sq.m. If its length is 50 m, find the length of the rope required to fence it.

Answer 1

First of all we need to find the breadth of the rectangle .

We know that,

Area= length * breadth

1800sq.m = 50m*breadth

breadth = 1800/50 =36m

We know that for fencing we need to find perimeter of that.

Length of rope required= Perimeter of the rectangle

Perimeter = 2*(length+breadth)

Perimeter =2*(50+36)m

Perimeter = 2*86

Perimeter = 172m

Length of the rope required to fence is 172 m.
