Answer:

  • The area is 4x² + 44x + 120

Step-by-step explanation:

Given

  • Dimensions of rectangle are 12 in and 10 in,
  • Width of the frame is x.

To find

  • The area of the framed photograph

Solution

Dimensions of the framed photograph are:

  • 12 + 2x and 10 + 2x

Area of the framed photograph is:

  • A = lw
  • A = (12 + 2x)(10 + 2x)
  • = 12*10 + 12*2x + 10*2x + 2x*2x
  • = 120 + 24x + 20x + 4x²
  • = 4x² + 44x + 120
