Create a tool for math calculations
It's time to build your tool. Let's imagine you run a small construction company and need to calculate the length of one side of a roof. If you know the lengths of two beams that support the roof at a right angle, you can use their lengths to calculate the length of the roof using the hypotenuse formula below. $$c = \sqrt{a^2 + b^2}$$

Petunjuk latihan
- Use the necessary decorator to define the function as a tool.
- To find the hypotenuse, use the
.split()method on theinputstring to extract the two other lengths of a right-sided triangle. - Convert each triangle side,
aandb, to floats and use.strip()to remove any extra spaces from the values. - Use Python's
mathmodule to square the lengthsaandb, sum their values, and find their square root to reveal the length of the roof.
