Answer:
Step-by-step explanation:
The perimeter (P) of a rectangle is equal to the sum of twice the length and twice the width.
For this problem, let x be the width.
Then because the length is 2 less than 3 times the width
The length is 3x - 2
Therefore, P = 2x + (2)(3x - 2) = 36
Solving this for x gives:
2x + 6x - 4 = 36
8x - 4 = 36
8x = 40
x = 5
Therefore, the width = x = 5 feet
And the length = 3x - 2 = (3)(5) - 2 = 13 feet
