What is the height of a triangle with a base of 13.2 ft and an area of 198 ft?
The formula to calculate area of a triangle is 1/2 bh. You're trying to find out what the height is, so let's fill in what we know.base=13.2 ft; area = 198 ft Putting these numbers into our formula, we get:1/2 (13.2) x ?(h) = 198 ft1/2 of 13.2 is 6.6 so if we divide this into 198 we get 30 ft.Let's check our work: 1/2 (13.2) x 30 = 198, true or false? It is true, so the height of the triangle must be 30 ft.
