Is the perimeter 72?
Yes. The perimeter is 72 inches.
To find the perimeter of the frame, we need to add up the lengths of all four sides. The formula for the perimeter of a rectangle is 2 * (length + width). In this case, the length of the frame is 22 inches, and the width is 14 inches.
So, the perimeter is:
2 * (22 + 14) = 2 * 36 = 72 inches
Therefore, the perimeter of the frame is 72 inches.
