6 divided by 812 is very difficult to do without using a calculator - I would suggest the bus shelter method, as I've shown in the photo attached, but it is still quite difficult to use that method without a calculator.
<em>If</em>, however, you mean 812 divided by 6, that is a lot easier to calculate using the bus shelter method - so, just in case, I've attached the method for that too.
6 divided by 812 = 0.007389...
Mean = sum of values / number of values
74 = x/32
2368 = x
70 = y/19
1330 = y
mean for female students = (2368 - 1330)/(32-19) = 79.85
C is the answer because with this kind of math the answer can be Neg or Postive <span />
The Original length of each side of square was 14.25 inches.

Perimeter of square after reducing 2 inches from each side

So,
The Original length of each side of square was 14.25 inches.
