Arturo Potts · Answer 1

9 feet

Step-by-step explanation:

15+15 = 30. 48 - 30 = 18. 18/2 = 9. If 48 is the perimeter than it should have 15 as the length and 9 as the width.

9 ft

Step-by-step explanation:

So let's assume the shape is rectangular.

The perimeter of the rectangle with dimensions l and w is: 2w+2l.

We are given 48 feet of wood so we want 2w+2l=48.

Manny wants l to be 15 so insert this into equation: 2w+2 (15) = 48.

Now we need to solve

2w+2 (15) = 48

Multiplying 2 and 15:

2w+30=48

Subtract 30 on both sides:

2w = 18

Divide both sides by 2:

w = 9

We want the width to be 9 ft.
