Heron's formula The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base, as seen in the figure below: A triangular prism is a stack of triangles, so the usualy triangle solving rules apply when calculating the area of the bases. It's possible to calculate that area also in angle-side-angle or side-angle-side version - probably you remember that every angle in the equilateral triangle is equal to 60 degrees (π/3 rad). If you don’t know the height or you may have no idea how to find out the height of the triangle, then you can use the below program to calculate the area of a triangle. Area = ½ (base) (height) Height = 2*Area/base. The basic formula to find the area of a given triangle is A = 1/2 × b × h, where b is the base and h is the height of the given triangle. Plug in the integer, or decimal dimensions in the area of a triangle formula A = 1/2 * b * h and solve for the area. If you know the length of one side (let’s call that the base) and you know enough to calculate the area, you know the height because the height is the area divided by the length of the base. Right triangle Calculator . The area of a right-angle triangle can be calculated according to the following formula: A = 1/2(bh) In plain english the area of a right angle triangle can be calculated by taking one half of the base multiplied by the height.
