Question

Nya is building a garden in her yard. She has 24 feet of fencing for her garden and wants it to be in the shape of a rectangle with a length of 3 feet. What does the width need to be for this to work?

Answer 1

Perimeter = 2·length + 2·width = 24.
So 2·3 + 2·w = 24 → 6 + 2w = 24 → 2w = 18 → w = 9.

The width should be 9 feet.
