The height is 4 feet the base is 16 and the opposite side of it is 4 You need to find the area This shape, btw is called a trapezoid
Let's call the top horizontal line, a the base, or bottom line, b the height is h The equation to solve for the area of a trapezoid is A = (a+b)* h/2 Fill in the given A = (4 + 16) * 4/2 A = (20) * 2 A = 40
