The formula for finding the area of a triangle 1/2 base * height. This time, we know the base and the area, so we have to find the height. Let's say the variable h represents height. 1/2 (4) * h = 16. 2 * h = 16. If you divide both sides of the equation by 2, you get h = 8. Therefore, the height of the triangle must be 8 inches with a base of 4 inches to get an area of 16 square inches. You can double check by doing: 1/2 (4) * 8 = 16. To check if its correct, solve it to get 2 * 8 is 16, which is accurate.
