To find the amount of rope David will need, we need to calculate the perimeter of the rectangular section. The formula for the perimeter of a rectangle is P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
In this case, the length (l) is 9 feet and the width (w) is 4 feet. Plugging these values into the formula, we get:
P = 2(9 + 4)
P = 2(13)
P = 26
Therefore, David will need 26 feet of rope.
David planted new grass seed in a rectangular section of his lawn that is 4 feet wide by 9 feet long. He wants to put a rope around that part of this lawn. How much rope will he need?
