a) a: 8π in2; b: 24π in2
b) a: 24π in2; b: 16π in2
c) a: 16π in2; b: 36π in2
d) a: 16π in2; b: 24π in2

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
