Answer:
A. 5 in
Step-by-step explanation:
Let w represent the width of the frame.
If the length is 3 inches longer than twice the width, it can be represented by 2w + 3.
Use the perimeter formula, p = 2l + 2w. Plug in the perimeter and 2w + 3 as l, and solve for w:
p = 2l + 2w
36 = 2(2w + 3) + 2w
36 = 4w + 6 + 2w
36 = 6w + 6
30 = 6w
5 = w
So, the width of the frame is 5 inches.
The correct answer is A. 5 in
