the right side of a sign measures 8 units and the bottom side measures 7 units. What is the area in square units of the sign?

The area of a rectangle is calculated by multiplying the length and width of the rectangle. In this case, the length of the sign is 8 units and the width is 7 units. Therefore, the area of the sign is:

Area = length x width
Area = 8 units x 7 units
Area = 56 square units

So, the area of the sign is 56 square units.
