Answer:
13.7 feet
Step-by-step explanation:
By using the Pythagorean Theorem, you can write 6^2 + x^2 = 15^2 with x being the length of the rectangle. Simplifying it would be 36+x^2=225. Subtracting 36 from both sides would result in x^2=189. Square rooting both sides would be x≈13.7477270849. Rounding to the nearest tenth, x=13.7 feet.
