The base of a parallelogram is twice as long as its corresponding height. If the area of the parallelogram is 144 cm2 , find the mentioned height.
Answer & explanation
Correct answer: option 2
We know that,
Area of parallelogram = Breadth × Height
We have,
Breadth = 2 × Height,
Area = 144 cm2
So according to the question,
= 144 = 2 (h×h)
= 72 = h2
= h = \(\sqrt {72}\)
= h = 6\(\sqrt {2}\) cm.
