HELP PLEASE!

A rectangular picture is twice as long as it is wide. If the
area of the picture is 288 in^2, what are its dimensions?

The dimensions of the picture are_____ in long by_____ in wide.

Answer 1

24 in long by 12 in wide.

Explanation:

l=2w

288=(2w)×w

288=2w^2

144=w^2

12=w

use w=12 to solve for l

l=2(12)

l=24
