*It helps to draw a diagram for these types of questions

Side length of photograph: x + 8

Width of frame: 2 in.

Area of a square: s^2

A = ((x + 8) + 2)^2

= (x + 10)^2

Therefore the area of the photograph with the frame is (x + 10)^2

Answer:

  • 8(x + 10) or 8x + 80

Step-by-step explanation:

Area of the picture:

  • (x + 8)²

Side of the photograph with the frame:

  • (x + 8) + 2*2 =
  • x + 12

Area of the frame:

  • (x + 12)² - (x + 8)² =
  • (x + 12 + x + 8)(x + 12 - x - 8) =
  • (2x + 20)(4) =
  • 8(x + 10)

or

  • 8x + 80
