Answer:
The width would be 10 inches.
Step-by-step explanation:
To find this, start by labeling the width of the rectangle as x. Now we can express the length as 3x - 5. Now use the perimeter formula and the known perimeter to find x (which is the width).
2l + 2w = P
2(3x - 5) + 2x = 70
6x - 10 + 2x = 70
8x - 10 = 70
8x - 80
x = 10
