Answer:

a. 29 cm

Step-by-step explanation:

We can find the length of the hypotenuse using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.

20² + 21² = h²

  • h: hypotenuse, calculate the square values.

400 + 441 = h²

  • Add the numbers.

841 = h²

  • Find the root for both sides.

29 = h
