Answer:
25 feet
Explanation:
Since there are 3 rectangles, we can simply combine them into one big rectangle. The small rectangle each had a length of 36, we can multiply that by 3 to get the length of our big rectangle. This gives us 108 as our length.
Since perimeter is found by 2*l + 2w, which is equal to 366 in this question, we can setup an equation like this:
2*108 + 2w = 366.
Now we can solve for w.
2w = 150
w = 75.
The width of the big rectangle was calculated as 75. However, the question asked for the width of the small rectangle, so we need to divide this number by 3, giving us 25 feet as our final answer.
