Let’s practice now calculating the area of a triangular metal sheet. In the example below the metal sheet provided has a base measuring nine feet and a height measuring seven feet. Please note that the height is measured perpendicular from the base to the corner opposite to the base. In order to calculate the area, we need to multiply the base, times the height, and divide this value by two. Taking the dimensions from this shape, we would multiply nine feet, by seven feet, which give us 63 feet, and then we divide the 63 feet by two, resulting in 31.5 squared feet.
