Question

A rectangle has dimensions of 3 feet by 1 foot. What is the length of the diagonal of the

rectangle? Is the length a rational or irrational number?

Answer 1

Explanation:

3^2 + 1^2 = c^2 (diagonal squared)

9 + 1 = c^2

10 = c*2

`√(10)` is the length

It is irrational because the decimal repeats forever
