Question

The area of a rectangle is 18 cm2^2 and the perimeter is 18 cm. What is the ratio of the length to the width?

Worked Solution

Possible dimensions if area = 18 cm2^2

18 ×\times 1 = 18, Perimeter = (18 + 1) ×\times 2 = 38

9 ×\times 2 = 18, Perimeter = (9 + 2) ×\times 2 = 22

6 ×\times 3 = 18, Perimeter = (6 + 3) ×\times 2 = 18 (correct)

∴\therefore Ratio of length : width
= 6 : 3
= {{{correctAnswer}}}
