Answer:

  • length: 10 +2x inches
  • width: 8 +2x inches
  • area: 4x^2 +36x +80 square inches

Step-by-step explanation:

The frame adds x to the picture on each side, so adds 2x to the length and 2x to the width.

The length is 10 + 2x.

The width is 8 + 2x.

__

The area is the product of length and width:

  A = LW = (2x +10)(2x +8) = 4x^2 +16x +20x +80

  Area = 4x^2 +36x +80 . . . square inches
