Answer:
40 cm^2
Explanation:
Area of rectangle = length * width.
Area of square = length^2
To find the area of the given shape, we must subtract the area of the square from the area of the rectangle.
Area of the given rectangle = 8 * 7 = 56 cm^2
Area of the given square = 4^2 = 16 cm^2
56 - 16 = 40 cm^2
