Question

The width of a rectangle is one half its length. The perimeter of the rectangle is 54 cm. What are the width and length of the rectangle?​

Answer 1

Let x = length

Then width = (1/2)x

Perimeter = 2(length) + 2(width) = 54

length + width = 27

So, x + (1/2)x = 27

(3/2)x = 27

x = 27(2/3) = 18 (1/2)x = 9

Answer: length = 18 cm and width = 9 cm
