Answer:
h = 12 units
Explanation:
Area of a Parallelogram = base × perpendicular height (A = b × h)
In the diagram above we can obtain the following:
- Area = 72 units²
- perpendicular height = h
- base = 6
(Please Note: the base of a parallelogram must be perpendicular to its height; in this case it is the side measuring 6 units that is perpendicular to the height)
Since A = b × h
⇒ A ÷ b = b ÷ b × h (dividing both sides by b)
⇒ h = A ÷ b (making h the subject of the eq'n)
thus h = 72 unit² ÷ 6 units
= 12 units
