Question

the measure of two adjacent sides of a rectangle is in ratio 11:10. If the perimeter of the rectangle is 84 cm, then find it's length and breadth.

Answer 1

Answer:

The ratio of length and breadth = 11:10 [The adjacent sides of a rectangle are its length and breadth]

Let the length be 11x and the breadth be 10x

So, 2 (11x + 10x) = 84

21x = 84/2

21x = 42

x = 42/21

x = 2

So the length is (11 x 2) = 22 cm and the breadth is (10 x 2) = 20 cm
