Question

A 5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches

Answer 1

Answer:

Perimeter = 28 + 8x inches

Step-by-step explanation:

Length of the photograph = 7 inches

Width of the photograph = 5 inches

Both the length and width of the frame are 2x inches larger than the width and length of the photograph.

Length of the frame = 7 inches + 2x inches

Width of the frame = 5 inches + 2x inches

Perimeter of the frame = 2(Length + width)

= 2{(7+2x) + (5+2x)}

= 14 + 4x + 10 + 4x

= 28 + 8x inches

Perimeter = 28 + 8x inches
