Mathematics for IGCSE & O level - Ratio And Proportion (Section 5 - No. 11)

A rectangular garden has a length to width ratio of 5:3. If the length of the garden is 20 meters, what is the width?

8 m

12 m

15 m

33.33 m

Since the length corresponds to 5 parts, and 5 parts = 20m, each part is 4m. Width = 3 parts, so 3 * 4 = 12 m.
