Hello!
If the ladder is placed 11 feet from the building, it will be slanted. The building, ground, and ladder will create a right triangle. We can use the Pythagorean Theorem to solve for the ladder (the hypotenuse). We will use a²+b²=c², where a and b are the building and ground, while c is the ladder.
60²+11²=c²
3600+121=√3721
√3721=61
Therefore, our ladder must be 61 feet long.
I hope this helps!
