Question

1. The length of the rectangle is 4 times its width. If the perimeter of the rectangle is 80 m, find the length and breadth of rectangle.

Ans_​

Answer 1

Step-by-step explanation:

let the breadth of rectangle be x m

length of rectangle=4x

perimeter of rectangle=2(l+b)

=>2(x+4x)=80

=>2×5x=80

=>10x=80

=>x=8

length is 32m and breadth is 8m

Answer 2

Answer:

Perimeter of a rectangle =2(l+b)

Let b=x,then l=4x

80=2(4x+x)

=80/2=4x+x

40=5x

X=40/5= 8

B=8

L=8*4=32
