Advanced MathEasy–MediumWidth of a garden twice as long as it is wide

Advanced Math practice question

A rectangular garden is twice as long as it is wide, and its area is 32 square metres. What is the width of the garden, in metres?

Answer: 4

With width w, the length is 2w and the area is 2w² = 32, so w² = 16 and w = 4.

Common wrong answers

If you answered 8
8 is the length, not the width.
If you answered 16
16 is w², not w.
If you answered 5.66
5.66 is √32, forgetting the factor 2.
