the image is a rectangle with a triangle on the right side of the rectangle and then a square attached to the bottom of the triangle.
The rectangles width is 12 ft and length is 4 ft and the square is 4ft in length and 4 feet in width
The total area of the rectangle is 12 ft * 4 ft = 48 square feet.
The area of the triangle is (1/2) * base * height = (1/2) * 4 ft * 4 ft = 8 square feet.
The area of the square is 4 ft * 4 ft = 16 square feet.
Therefore, the total area of the shapes combined is 48 square feet + 8 square feet + 16 square feet = 72 square feet.
