Question

The area of the rectangle is 2880 sq.M. The ratio of the sides is 5:4, the perimeter is:

Answer 1

Let the sides be 5x & 4x

Area of the rectangle = 2880m²

Length *breadth= 2880

5x*4x= 2880

20x²= 2880

x²= 2880/20

x²= 144

x = √144

x= 12

Sides are 5x = 5*12=60cm

& 4x=4*12= 48cm

Therefore, perimeter =2(length+breadth)

= 2(60+48)

= 2*108

= 156cm
