Holly wants to make a frame for painting. The painting is square and has an area of 225 square inches. The framing material costs $1.35 per inch. How much will Holly spend framing the picture?

Answer 1

Since the painting is square, each side is √225 = <<15=15>>15 inches.
Since the painting is square, the frame will also be square which means it will also be 15 inches on each side.
The area of the frame is (15+2*1.35)(15+2*1.35) = (15+2.7)(15+2.7) = 14.7*14.7 = <<14.7*14.7=216.09>>216.09 square inches.
Holly will therefore spend 1.35*216.09 = <<1.35*216.09=291.4285>>291.4285 dollars framing the picture. Answer: \boxed{291.43}.
