Question

How do you express in radical form the length of the diagonal of a square whose sides are each 2 meters long?

Answer 1

I found `2sqrt(2)m`

Explanation:

You can use Pythagora's Theorem where the diagonal `d` is given in terms of the length of the two sides `s` as:
`d^2=s^2+s^2=2s^2`
`d=sqrt(2s^2)`
`d=sqrt(8)=2sqrt(2)`
