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

1 answer:

8 0

A = bh
b = 4h
A = 324

324 = 4h * h
324 = 4h^2
324/4 = h^2
81 = h^2
sqrt 81 = h
9 = h

b = 4h
b = 4(9)
b = 36

so the height (h) = 9 cm and the base (b) = 36 cm
