Question

The perimeter of avrectangular field is 480 meters and the ratio between the length and breadth is 5:3 . The area of the field is

Answer 1

perimeter of rectangle=2(l+b)
480=2(5x+3x)
480=10x+6x
480=16x
480/16=x
x=30

then,length=5x=5*30
=150
width=3x=3*30
=90

area of field =l*b
150*90
=13500
