Manny has 48 feet of wood. He wants to use all of it to create a border around a garden. The equation can be used to find the length and width of the garden, where l is the length and w is the width of the garden. If Manny makes the garden 15 feet long, how wide should the garden be? 9 feet 18 feet 30 feet 33 feet

Respuesta :

Answer:

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.
