A composite shape is made up of a rectangle, triangle, and square. A horizontally aligned rectangle has a length of 12 feet and width of 4 feet. A right triangle adjoins the rectangle on the right side, with the vertical side common to the rectangle. A square with a side of 4 feet adjoins the right triangle along the bottom. Right angle marks are located in the four corners of the rectangle and the square, and also in the triangle where the base and vertical side meet.

The area of Annika's design can be found by calculating the sum of the areas of the rectangle, triangle, and square.
The area of the rectangle is length x width = 12 ft x 4 ft = 48 square feet.
The area of the triangle is (base x height) / 2 = (4 ft x 4 ft) / 2 = 8 square feet.
The area of the square is side x side = 4 ft x 4 ft = 16 square feet.
Adding up these areas, the total area of Annika's design is 48 square feet + 8 square feet + 16 square feet = 72 square feet.
