Yakvenalex [24]

Answer:

Height=12 Units

Step-by-step explanation:

Given a parallelogram with base b, and a perpendicular height, h. The area of the parallelogram is derived using the formula:

Area of a parallelogram=Base X Perpendicular Height

Given an area of 72 Units Squared.

Since I am not certain of the length of the base given:

If b=6

Area=bh

72=6h

Dividing both sides by 6

h=12 Units.

Height=12 Units

You can use the given formula to solve for the height,h of the parallelogram given any base b.
