Answer:
(24 + 8x) inches
Step-by-step explanation:
Length of the photograph = 7 inches
Width of the photograph = 5 inches
The border of the frame measure x-inches on all the sides, so this mean the dimensions of the frame would be:
Length of the frame = (7 + 2x) inches
Width of the frame = (5 + 2x) inches
Since the shape of the photograph frame is rectangular, the perimeter will be calculated as:
Perimeter = 2(Length + Width)
Using the values, we get:
Perimeter = 2(7 + 2x + 5 + 2x)
= 2 (12 + 4x)
= (24 + 8x) inches
Thus, the perimeter of the frame would be (24 + 8x) inches inches
