Question

The perimeter of a rectangular swimmimg pool is 200m . Its length is 4m more than twice its breadth . What is the length and the breadth of the pool?

Answer 1

Perimeter of the rectangular pool=200m

Let the breadth be x

Therefore, length=2x+4

Perimeter of a rectangle=2×(L+B)

200m=2×(x+2x+4)

200m=2x+4x+8

200m-8=4x+2x

192m=6x

x=192/6=32

Breadth=l=32m

Therefore, length=2×32+4=68m

To check,

2×(L+B)=200m

2×(32+68)=200m

64+136=200m
