Question

A playground is 30 m longer than it is wide. If its perimeter is 300 m, what is its area!
.​

Answer 1

let the width of the playground be x

Then length will be 30+x

300= 2 (30+x + x)

300=60+2x+2x

300=60+4x

300-60=4x

240=4x

x=60

area of playground= l×b

=60×90

=5400

The area of playground is 5400msq.

Answer 2

Answer:5400

Step-by-step explanation:

300= 2 (30+x + x)

300=60+2x+2x

300=60+4x

300-60=4x

240=4x

x=60

area of playground= l×b

=60×90

=5400
