To find the perimeter of a rectangle, the formula used is P = 2(length + width). In this case, the length of the rectangular frame is 36 inches and the width is 24 inches.

First, you add the length and width together:

36 inches + 24 inches = 60 inches.

Next, you multiply by 2 to find the perimeter:

2 x 60 inches = 120 inches.

This calculation gives a total perimeter of 120 inches, confirming that the correct answer is indeed the first choice. Understanding this formula is key, as it can be applied to any rectangle, allowing for quick perimeter calculations in similar problems.
