Let the width be w, then length = 2w - 1
Area = length times width = w(2w - 1) = 21.
Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0
Solving the quadratic equation gives that w = 3.5.
Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.

Answer:
=2w2+9w−35
Step-by-step explanation:
(2w+−5)(w+7)
(2w)(w)+(2w)(7)+(−5)(w)+(−5)(7)
2w2+14w−5w−35
2w2+9w−35
