In the figure, the two bottom corners of a parallelogram are joined to a point on the top side.


The area of the dark triangle in the figure is 5 square centimeters. What is the area of the parallelogram?

From the given picture we can see that a triangle is drawn inside the parallelogram.

The area of the triangle is 5 cm2


We can see that the base and height of both the triangle and parallelogram is same


The area of the triangle =


5 = ( base × height)


10 cm2 = base × height


The area of the parallelogram = base × height


= 10 cm2
