The area of the composite figure is 70 cm^2
The area of the figure = area of rectangle + area of a triangle
Area of rectangle = length * width
Area of rectangle = 10 * 5
Area of rectangle = 50 square centimeters
Area of triangle = 0.5(5)(8)
Area of triangle = 20 square cm
Area of the figure = 50 + 20
Area of the figure = 70 square cm
Hence the area of the composite figure is 70 cm^2
