Question

A rectangle has dimensions . by . What is the length of the diagonal of the rectangle?

Answer 1

`3√(5)` units

Explanation:

Use the Pythagorean Theorem to find the diagonal:

You have that the sides are 3 and 6, so a = 3 and b = 6, which means:

`3^2 + 6^2 = c^2\\9 + 36 = c^2\\45 = c^2\\c = 3√(5)`
