The height of a parallelogram is 3 times the base. The base measures 4.5 cm

What is the area of the parallelogram?

The area is 60.75 cm²

Step-by-step explanation:

Let h = 3b (height is 3 times the base)

Since the base is 4.5 cm, the height is 3 (4.5 cm) = 13.5 cm.

The area of a parallelogram is A = L·H, which here is:

A = (4.5 cm) (13.5 cm) = 60.75 cm²
