Question

The length of a rectangle is twice its width.The area of the rectangle is 44.5cm^2

Answer 1

let the width = x cm then the length will be 2x cm.

area = length * width = x * 2x  = 44.5

so we have to solve  2x^2 = 44.5

x^2 = 22.25

x =  4.717 cm  = width

so length = 2*4.717  =  9.434

answer is width = 4.72 and length =  9.43 cm  to  nearest hundredth
