Solution

The correct option is D 9.66
First, calculate the number of complete boxes which is coming to be 4. For incomplete boxes give a number based on how much part of the box is included in the area. Half squares can be taken as 1/2
2 * 1/2 =1
Squares convening less than half can be taken as 1/3
4 * 1/3 =4/3
Squares covering more than half it can be taken as 2/3.
5 * 2/3= 10/3
Adding all the values will give the total area
4 + 1 + 4/3 + 10/3 = 9.66 sq km.
