Use the image to answer the question.

An illustration shows a parallelogram with top side as 7 centimeters. A perpendicular dotted line from the top left vertex to the bottom side is 12 centimeters. The perpendicular line makes one right angle symbol with the top side and two right angle symbols with the bottom side.

What is the area of the quadrilateral?

The area of the parallelogram can be calculated as the product of the base and the height.

In this case, the base of the parallelogram is the top side which is 7 centimeters long, and the height is the distance from the top side to the bottom side along the perpendicular line, which is 12 centimeters long.

Therefore, the area of the parallelogram is:
Area = base x height
Area = 7 cm x 12 cm
Area = 84 square centimeters

So, the area of the quadrilateral is 84 square centimeters.
