Use the image to answer the question.

A coordinate plane shows both the axes ranging from negative 9 to 9 in increments of 1. A rectangle is plotted on the graph. The plotted points of the rectangle are as follows: left parenthesis 3 comma negative 3 right parenthesis; left parenthesis 7 comma negative 3 right parenthesis; left parenthesis 7 comma negative 8 right parenthesis; and left parenthesis 3 comma negative 8 right parenthesis. A solid line connects the plotted points.

The area of the rectangle formed by the four plotted points can be calculated by finding the length and width.

Length = 7 - 3 = 4
Width = -8 - (-3) = -5

To find the total area when adding a second panel to the right, we need to double the length:
New Length = 2(4) = 8

The total area of the two solar panels will be:
Total Area = New Length x Width
Total Area = 8 x (-5) = -40 sq. ft.

Therefore, the correct answer is 40 sq. ft.
