Manny has 48 feet of wood. He wants to use all of it to create a border around a garden. The equation 2l + 2w = 48 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?

the perimeter of the garden is already found 
it is 2l + 2w = 48, the half of it is P/2= 24
but we know that  P/2=l + w, so we can find w=P/2-l =24 -15= 9 feet
the answer is A. 9 feet

Answer:

The wide of a garden should be 9 feet

A is correct

Step-by-step explanation:

Manny has 48 feet of wood.

He wants to use all of it to create a border around a garden.

The equation 2l + 2w = 48

where,

l is the length of the garden.

w is the width of the garden.

If Manny makes the garden 15 feet long.

Thus, l=15 feet

We need to calculate w=?

Put l=15 into equation 2l + 2w = 48 and solve for w

2(15) + 2w = 48

30 + 2w = 48

2w = 48 - 30 = 18

w = 9  feet

Hence, The wide of a garden should be 9 feet.
