The given figure can be divided to two rectangles
The first will have the dimensions of 10 and 2
The second will have the dimensions of ( 9 - 2 ) and ( 10 - 6 )
So, the area of the first rectangle = 10 * 2 = 20 cm^2
The area of the second rectangle = (9-2) * (10-6) = 7 * 4 = 28 cm^2
So, the total area = 20 + 28 = 48 cm^2
