Question

The length of a rectangular plot is 1.5 times it's that 20presant of its perimeter is 20 m the area of a plot is what

Answer 1

let perimeter be x
20/100 x=20
implies,x=100
length=1.5(breadth)
implies,2(1.5b+b)=100
           2(2.5b)=100
              5b=100
              b=20
l=30
implies,area of plot=30*20=600
