$$\Huge A = l•w$$

Answer 4

The problem states:

The length of the fountain is (4w-8) in ft = l

and the width is w feet. = w

What is the length of the fountain

if it's area is 672 ft^2? = A

Replace the symbols with the words and solve for w, then answer what the question is asking for which is
