The Pythagorean Theorem Says That the Length of the Hypotenuse $178.2 \mathrm{~cm}$

Short Answer

The Pythagorean Theorem says that the length of the hypotenuse is the root of the sum of the squares of the two legs. Therefore, the length of the hypotenuse of a right triangle with legs $178.2 \mathrm{~cm}$ and 78.4 $\mathrm{cm}$ long is $\sqrt{(178.2)^2+(78.4)^2}$ . Calculate this length.
