Question

A playground is 40m longer than it is wide if its perimeter is 272m what is its area?

Answer 1

length of the playground = 40 metre longer than its width
perimeter equal 272 metre
bread is equal to 72 minus 40

Answer 2

let the length be x,breadth be x-40
perimeter=2(l+b)
272=2(x+x-40)
272=4x-80
4x=272-80
x=192/4
x=48m
length=48m
breadth=x-40m=48-40=8m
its absolutely right
area=lxb
area=48,multiplied to 8
area=384msquared
