You can figure out if two fractions are bigger by just cross multiplying the numerator and denominator of each fraction.

Multiply the 5 and 7, and then the 3 and 12. Be sure to start with the numerator of the first fraction.

5 * 7 = 35, 3 * 12 = 36
So

is bigger.
Answer:
20 feet.
Step-by-step explanation:
Pythagoreans theorem states that a^2 + b^2 = c^2
a = 12, squared = 144
b = 16, squared = 256
144 + 256 = 400
√400 = 20
20 feet is the answer.
