Question

play ground is 30 metre longer than it is wide it if it perimeter is 300 metre what is its area​

Answer 1

Answer:5400

Step-by-step explanation:let width be 'b' then length = b+ 30

By the problem, 2(b+30+b)=300

Thus b=60.

Thus,l=60+30=90

Area=l*b= 90*60=5400

Answer 2

Answer:

let it's breadth be x

than length = x + 30

perimeter = 2(l+b)

300 = 2(x +30 + x)

300 = 2(2x + 30)

150 = 2x + 30

120 = 2x

x = 60

length = 90

breadth = 60

area = LB

        =90*60

        =5400
