The base of a parallelogram is twice as long as its corresponding height. If the area of the parallelogram is 144 , find the mentioned height.
Explanation:
Let the height of the parallelogram = h, and its base will be 2h
Area of a parallelogram = base × height
⇒ 144 = 2h × h
⇒ 72 = h2
⇒ h = 6√2
Hence, option (a).
