Use the image to answer the question.
A coordinate plane shows both axes ranging from negative 2 to 8 in increments of 1. Four labeled points are plotted and joined to form a rectangle. The four points are labeled as upper A, upper B, upper C, and upper D, respectively, and are plotted at coordinates left parenthesis 0 comma 0 right parenthesis, left parenthesis 0 comma 4 right parenthesis, left parenthesis 5 comma 4 right parenthesis, and left parenthesis 5 comma 0 right parenthesis, respectively. All four points are connected by solid lines to form a rectangle. The area inside the rectangle is shaded.
Calculate the perimeter, in feet, to determine how much fencing is required to enclose the garden shown in the image.

The perimeter of a rectangle is found by adding the lengths of all four sides.
First side: AB = 4 units
Second side: BC = 5 units
Third side: CD = 4 units
Fourth side: DA = 5 units
Adding all the sides together:
4 + 5 + 4 + 5 = 18
Therefore, the perimeter of the rectangle is 18 feet.
