Answer: x + 3feet
Explanation:
From the question, Emmanuel sections a part of his house backyard in order to build the rectangular stone patio for his grill. We are told that the length of the base is going to be 3 feet more than the width and the width has been defined as x.
Since the length of the base will be 3 feet more than the width and the width is x. Therefore, the length will be:
Length = x + 3feet
