First we have to count the full squares and area of them are 9(3*3) multiply by 5 is equal to 45.Then we have to count more than half squares as full squares and multiply 9 with 8 which is equal to 72. Then we have to remove the less than half squares. And the last step is just add 45 and 72 which is equal to 117 sq.cm
