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

9 feet
18 feet
30 feet
33 feet

Answer:

[tex]2l + 2w = 48[/tex]

if garden is 15' long

[tex]2(15) + 2w = 48 \\ 30 + 2w = 48 \\ 30 - 30 + 2w = 48 - 30 \\ 2w = 18 \\ \frac{2w}{2} = \frac{18}{2} \\ w = 9 \: feet \: wide[/tex]
