Answer 1

2h.

A = ½(b)(h). Substituting known facts gives 36 =½(2h)(h), which means that 36 = h2

and therefore h = 6 inches, height = 12 in.

Explanation:

So let's designate height as h and base as 2h.

A = ½(b)(h). Substituting known facts gives 36 =½(2h)(h), which means that 36 = h2

and therefore h = 6 inches, height = 12 in.
