Because you are dividing fractions, you take the reciprocal of the denominator and multiply it to the numerator, giving you (9/4) x (4/3). the 4's cancel out, leaving you with 9/3, which is 3.

So first you need to find the surface area of the cake pan in the recipe:

9 times 11 + (9 times 2)2 + (2 times 11)2=99+36+44 which you can figure out yourself. 

The second one is:
 
10 times 10+(10 times 10)2+(10 times 2)2= 100+200+40 which you can also figure out yourself. 

I am guessing you cannot use the pan you have for your recipe.
