A pizzeria sells a rectangular 18 X 24 inch pizza for the same price that it sells its large 24" diameter pizza. If both pizzas have the same thickness, which option gives the most pizza for the money.
Gosh I'm really rusty on my geometry. Can you give me an idea of how to go about this?

If they have the same thickness and the ingredients are proportional to the area, I would calculate the area of each.
For the rectangular pizza,
Ar=18*24=402 sq. inches
For the circular pizza,
Ac=π(24²)/4=452.4 sq. inches.
Make your pick before picking up the telephone. 
Thanks so much. Any ideas on my other question?

You're welcome!
I posted something on the other one too!
