Question

Theside of a rectangular field are into the ratio 9 :7 and its perimeter is 144 metres find the sides

Answer 1

let the common multiple be x

sides of rectangular field is 9x and 7x

perimeter = 9x +9x +7x+7x

144 = 32x

x = 144/32

x = 4.5 m

sides = 9x and 7x

= 9×4.5 and 7×4.5

= 40.5m and 31.5m
