Question

the length of a rectungular plot is 1.5 times its breadth.20%of its perimeter is 20 metres.find the area of it​

Answer 1

breadth of rect be=x

length be=1.5*x

if 20percent=20

then 100percent=100m

perimeter=2*(l+b)

2*(x+1.5x)=100

2*2.5x=5x=100

5x=100

x=100÷5

x=20

breadth=20

l=1.5*20

l=30m
