The quick math is (13/15)^2 =0.7511. I always do this calculation when ordering pizzas. Most places near me carry a 12 inch and a 16 inch. The 16 inch is usually only $3 more when it is 1.77x bigger. [(16/12)^2= 1.77]

A bit off topic, but the expression 1.77x bigger bugs me. Isn't it technically only 0.77x bigger? It's 1.77x the size. But it's only 77% bigger.
