Determine the exact number of square inches of pizza I will get from 2- 7 pizzas and then from a 14

pizza, letting me know the outcome of your computations.

Then, determine how many more square inches of pizza I will get if I order 1- 14 pizza, instead of 1- 7 pizza, again,

letting me know the outcome of your computations.

Also, if I order the 14 pizza, beside myself, I will have to share it equally with 5 friends.

Exactly how much pizza will I get to eat?
