Question

The area of a rectangle is 36 cm2^2 and the perimeter is 30 cm. What is the ratio of the width to the length?

Worked Solution

Possible dimensions if area = 36 cm2^2

36 ×\times 1 = 36, Perimeter = (36 + 1) ×\times 2 = 74

6 ×\times 6 = 36, Perimeter = (6 + 6) ×\times 2 = 24

4 ×\times 9 = 36, Perimeter = (4 + 9) ×\times 2 = 26

12 ×\times 3 = 36, Perimeter = (12 + 3) ×\times 2 = 30 (correct)

∴\therefore Ratio of width : length
= 3 : 12
= {{{correctAnswer}}}
