A right triangle with hypotenuse 28 cm and one side 13 cm will have the other side of length √(28

Because the base of the ladder is 9 cm from the ground, the top of the ladder will be

^{2}- 13^{2}) = √615 ≈ 24.8 cm.Because the base of the ladder is 9 cm from the ground, the top of the ladder will be

**33.8 cm**from the ground.
