Question

The sides of a rectangle are in the ratio 4:3 and its area is
$108cm {}^{2}$
The breadth of the rectangle is ___ cm.​

Answer 1

Answer:

breadth= 3a= 3×3=9 cm

Step-by-step explanation:

ratio of l:B = 4:3

let length 4a

breadth = 3a

area= l×b = 108 sq cm

4a×3a= 108 sq cm

12a^2 = 108 sq cm

a^2 = 108/12

a^2=9

a=3 cm

breadth= 3a= 3×3=9 cm

The breadth of the rectangle is 9 cm.
