Question

If a 16 in. by 24 in. picture has a wooden frame "x" in. wide surrounding it, what equation can be used to find the total area of the picture and frame? ...?

Answer 1

Area = width x length

Area = (16+2x)*(24+2x)

Answer 2

The total area of the the picture and frame is given by the equation A = (16 + 2x)(24 + 2x) = 384 + 32x + 48x + 4x^2 = 4x^2 + 80x^2 + 384
