Use the image to answer the question.
An illustration shows a parallelogram with top side as 10 centimeters. A perpendicular dotted line from top left vertex to the bottom side is 8 centimeters. The perpendicular line makes one right angle symbol with top side and two right angle symbols with the bottom side.
What is the area of the quadrilateral?
cm2
The area of a parallelogram can be calculated using the formula: Area = base x height.
In this case, the base of the parallelogram is the top side, which is 10 centimeters. The height of the parallelogram is the length of the perpendicular dotted line, which is 8 centimeters.
Therefore, the area of the quadrilateral is: 10 cm x 8 cm = 80 cm2.
