Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim’s head to the furthest tip of the shadow is 13 feet. Expand Image [Not drawn to scale] What is the length of Fahim’s shadow? Round to the nearest tenth of a foot.

Fahim’s height and his shadow form the two perpendicular sides of a right triangle, and the 13-foot distance is the hypotenuse. By the Pythagorean theorem, the shadow length is √(13² − 6²) = √133 ≈ 11.5 feet. The correct choice is 11.5 feet.
