Can you find the base and height measurements for a triangle if the area is 22?

No. I can only find the height in terms of the base (and area) of the triangle, or the base in terms of the height (and area) of the triangle. Specifically, since: area = 1/2 x base x height ⇒ 22 = 1/2 x base x height ⇒ 44 = base x height I can rearrange that to: height = 44 ÷ base or base = 44 ÷ height For example, the triangle could have a base of 11 units and a height of 4 units; alternatively, the triangle could have a base of 10 units and a height of 4.4 units; or, the triangle could have a height of 2 units and a base of 22 units; etc.
