Answer:
i believe it is the last option.
Explanation:
square units are units of area, so you'll want to find the SIDES and use those.
144 squared units would be 12 units per side.
25 would be 5, 169 would be 13.
pythagorean theorem is a^2 + b^2 = c^2, generally c is shown as the hypotenuse.
12^2 + 5^2 = 13^2 would be the last option given.
