Question

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

Answer 1

Let the adjacent sides of the rectangle be in ratio=-11x & 10x

Given,perimeter=84cm

Perimeter of a rectangle=2(l+b)

=>84=2(11x+10x)

=>84=2(21x)

=>84=42x

=>84/42=x

=>2=x

Then,Length=11*2=22cm

Breadth=10*2=20cm

.
