Question

The length of a rectangular garden is twice the width. If the perimeter is smaller than or equal to 900 feet, what is the greatest possible width of the garden.

Answer 1

Length (L): 2w

width (w): w

Perimeter (P) ≤ 2L + 2w

900 ≤ 2(2w) + 2(w)

900 ≤ 4w + 2w

900 ≤ 6w

150 ≤ w

Answer: 150 ft
