Which is the length of the diagonal of a rectangle with side lengths of 5 and 12 centimeters?

Answer 1

13 cm

Explanation:

The diagonal of a rectangle forms a right triangle; where the diagonal is a hypotenuse, and two sides of the rectangle are legs.

Using pythagorean's theorem (
`a^2 + b^2 = c^2`), we can say:

`5^2 + 12^2 = c^2\\25 + 144 = c^2\\169 = c^2\\13 = c`

The hypotenuse is equal to 13cm.
