Question

The area of a rectangle is 108 cm2. If its length is 12 cm, the ratio of its breadth to its length is

Answer 1

Area = 108
Length = 12
Then,
Length x breadth = 108
12 x b = 108
b = 108/12
b = 9 cm
Ratio = 9/108
1:12

Answer 2

let the breadth be x
area of rectangle =lxb
108=12*x
x=9
required ratio =9/12
=3:4
