Margarita [4]

Answer:

Step-by-step explanation:

From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have

l = w + 3, where

l = length of the garden

w = width of the garden

Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as

W(w) = 2, where

W(w) = width of the garden.

That's all the parameters given in the question
