The length of rectangular garden is 6 feet longer than the width. If the area of the garden is 16 square feet, find the length a

Lyrx [107]

Length = x + 6

Width = x

Area = 16 ft^2

The formula needed is A = L•W.

Here is the set up:

16 = (x + 6)(x)

16 = x^2 + 6x

x^2 + 6x - 16 = 0

Solve for x. After finding x, plug into the definition I gave above for length and width to find your answer.
