Question

The length of a rectangular plot is 1.5 times its breadth 20 of its perimeter is 20.meters.the area of the plot is

Answer 1

Answer:

let the perimeter be x

20%of x = 20

1% of x = 20/20=1

100% of x = 1×100=100m

∴ perimeter is 100m

let the breadth be x

length =1.5x

perimeter = 2(length +breadth)

100m= 2 (1.5x+x)

100m = 5x

x= 20m

breadth = 20m

length = 1.5×20= 30m

area = length × breadth

area = 20×30m²= 600m²
