Answer:

486 ft²

Step-by-step explanation:

w = width = 16 feet.

Plug in 16 to each w in the trinomial given:

2(16²) - 16 - 10

Simplify. Remember to follow PEMDAS. First, solve the parenthesis:

(16²) = 16 * 16 = 256

256 x 2 = 512

512 - 16 - 10 = 512 - (16 + 10) = 512 - 26 = 486

486 ft² is your answer.
