Composite shape: Small rectangle on top of a square. Measurements: 3ft. 3ft. 1 ft. 4ft. 6ft. The area of the shape(s) is 57 square feet
To find the area of the composite shape, we first need to find the individual areas of the small rectangle and the square.
Area of small rectangle = 3 ft x 1 ft = 3 square feet
Area of square = 4 ft x 4 ft = 16 square feet
Total area of the composite shape = Area of small rectangle + Area of square
Total area = 3 square feet + 16 square feet
Total area = 19 square feet
However, this total area is not equal to 57 square feet as provided in the question. This means there might be a mistake in the given measurements or in the calculation.
