The answer is 3.46 meters
You can get the answer by using the pythagorean theorem, since the ladder and the wall form a right triangle.
c^2 = a^2 + b^2
4^2 = 2^2 + b^2
16 = 4 + b^2
12 = b^2
b = sqrt(12) or 3.46 meters
The two numbers that multiply to get 9 and add up to get 10 is 9 and 1.
The correct answer is "3".
That is false, because you would measure with kilograms.
