What is the area of the parallelogram?

A parallelogram with base of 20 centimeters, height of 15 centimeters, and side length 21 centimeters.

Respuesta :

A parallelogram is just a rectangle with a cut off triangle on one side which has been moved to the other side so it’s just base * height as no area has been lost.
20 * 15 = 300
