A rectangular plate measures 3 ft by 4 ft. What is the length of its diagonal?

Think of the diagonal as the hypotenuse of a right triangle formed by the rectangle’s sides. Using the Pythagorean theorem, the diagonal d satisfies d^2 = 3^2 + 4^2 = 9 + 16 = 25, so d = sqrt(25) = 5. Therefore, the diagonal length is 5 feet. This rectangle mirrors the classic 3-4-5 right triangle, which is why 5 feet is the correct length.
