The given composite shape can be divided to rectangle and triangle
The dimensions of the rectangle are 5 cm and 6 cm
So, the area of the rectangle = 5 * 6 = 30 square cm
The triangle has a base of 5 cm and a height of 4 cm
So ,the area of the triangle = 0.5 * 5 * 4 = 10 square cm
So, the area of composite shape = 30 + 10 = 40 square cm
