It's area that matters, or course.

For a round pan:

1) Take half the diameter (half of 10 in your case, or 5)
2) Multiply it by itself (5x5 = 25)
3) Multiply by 3.14 = 78 sq inches appx.

For rectangular, just multiple length by width:

13 x 9 = 117 sq inches.

So 1.5 times as large is just right.
