Question

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

Answer 1

So the base is 45, right?

Answer 2

How did you get that?

Answer 3

nevermind Cal.. I already got it my friend showed me.. but Im still confuse tho...

Answer 4

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

Answer 5

yeah I got that too.. well I didnt get that answer, my friend showed me.. lol

Answer 6

Thanks Cal
