Question

The measure of 2 adjacent sides of a rectangle is in the ratio 11:10 . If the perimeter of the rectangle is 84 cm , then find its length and breadth

Answer 1

Answer:

let the common ratio be x

therefore sides become 11x, 10x.

applying the perimeter formula

p=2(l+b)

we get,

84=2(11x+10x)

84=42x

x=2

therefore the sides become 22 and 20.

2(22+20)=84.

hence verified mate.
