Question

The perimeter of a rectangular field is 480 meter. And the ratio between the length breadth us 5:3. The area if the field is ?

Answer 1

Let length=5x and,
Breadth=3x.
Perimeter of rectangle=2 (l+b)
480=2 (5x+3x)
480=2*8x
480=16x
480/16=x
=>x=30.
Length=5x=150 m
Breadth=3x=90m
We know that,
Area of rectangle=l*b
=150*90=13500m^2.
Therefore,area of field is 13500m^2.
