Answer 1

• The area is 4x² + 44x + 120

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
