The answer should be D: Zero. A triangle has three sides. Two of them are called the legs and the last longest one is called the hypotenuse. You have to do this equation: l^2 + L^2 = h^2 The sum of the legs to the power of 2 should equal the hypotenuse to the power of 2 7(7) + 2(2) = 10(10) 49 + 4 = 100. This is false. So you cannot make a triangle with these three side lengths.
