Luke is planning to lay two decorative pieces of wood across the 12-inch by 24-inch rectangular glass centerpiece of a cabinet.
Each piece will lie on a diagonal of the centerpiece. Select a number from the drop down menu to correctly complete the statement. Each piece of wood should have a length of approximately how many inches.
What you are looking for is the hypotenuse of a right triangle. If you have a 12 x 24 rectangle, these would be the sides of the triangle and we would use Pythagorean Theorem to find the hypotenuse. a^2 + b^2 = c^2 12^2 + 24^2 = c^2 144 + 576 = c^2 720 = c^2 take the square root of both sides c = sqrt(720) c = 26.8 inches is the approximate answer. I don't know what your choices are but one should be close to this answer.
