the length of a rectangular painting is 2 times its width. the painting is mounted in a frame that extends 2.5 inches on all sides. if the framed painting covers 150 in^2 of wall space, what is the length and width of the painting alone?

a.length=10 in width =5 in
b.length=5 in width=10in
c.length=20 in width=10 in

w = x
l = 2x

(x+5)(2x+5) = 150

l = 10
w = 5
