C. 30 feet
D. 33 feet

Respuesta :

I wanna say it would be 30

Answer:

A. 9 feet

Step-by-step explanation:

The garden would be in form of a rectangle and as such will have 2 equal lengths and 2 equal width.

The equation to be used to find the length l and width w of the garden is same as the perimeter of a rectangle given as

= 2(l + b).

If the garden is 15 feet long, the perimeter is equal to the total length of wood Manny has which is 48 feet. Hence

48 = 2(15 + w)

24 = 15 +w

w = 24 - 15

w = 9.

The garden is 9 feet wide.
