The base of a parallelogram is four times its height. If the area of the parallelogram is 324 cm², whats base and height ?

Question

allank · Answer

Hint: Area of a parallelogram = base*height
Try setting the height to be an unknown. Maybe x. Can you solve now?

Okay, let height be x so the base will be 4x (four times the height)
Area=base*height
324=4x*x=4x^2=(2x)^2
Find the square root of both sides
$$\sqrt{324}=2x$$
Thus
18=2x
Hence 
x=9

Thus the height = x =9, and the base = 4x = 36.
