2. Compute the area of a triangle (TriangleArea). Get both base and height from the user in inches (do not use the Scanner class), then calculate the area (formula below). Print out the area of the triangle (to four decimal places, but if they are trailing zeros, do not print). Calculate and print out the percentage of the length of the base with the area. In other words, divide the base by the area. Ensure the percentage is in the correct format using the NumberFormat class.
