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 area

Answer 1

Answer:

440 cm^2

Step-by-step explanation:

let say one side = 11x

then other side = 10 x

Perimeter = 2*(11x +10x) = 2* 21x = 42 x

42 x = 84

x = 2

11x = 11* 2 = 22 cm

10x = 10 *2 = 20 cm

Area = 22*20 = 440 cm^2
