The base of a triangle is equal to 4 what is the height of the triangle if the area is 28?

If the base of a triangle is b and the height of the triangle is h, the area of the triangle is given by the formula: area = 0.5 x b x h.

As such, in your case we have 28 = 0.5 x 4 x h, which means that h = 14.
