The base of a parallelogram is four times its height. If the area of the parallelogram is 324 cm², find the base and height. Enter the numerical answers only with the base first, separated by a comma and a space like this; 1, 2

Ok. The formula for the area of a parallelogram is bh. The base is 4x. The height is x. \[A = 4x \times x \implies 4x^2\]\[342 = 4x^2\]\[81 = x^2\]\[x = 9\]Therefore, 4x = base 4(9) = base = 36 height = x = 9
