You design the wooden picture frame and paint the front surface.

Hitman42 [59]

Answer:

a) 8x + 28
b) 68 in²

Step-by-step explanation:

Area of the frame with picture:

A = lw
A₁ = (x + 4)(x + 7) = x² + 11x + 28

Area of the picture:

A₂ = x(x + 3) = x² + 3x

Area of the wooden frame is the difference of the above values:

A₃ = A₁ - A₂
A₃ = x² + 11x + 28 - x² - 3x
= 8x + 28

When x = 5, the picture frame area is:

A₃ = 8*5 + 28 = 40 + 28 = 68 in²
