Question

How do you figure out a diagonal measurement of a rectangle if width is 14' and the height is 5'?

Answer 1

You use the Pythagorean Theorem (`a^2 + b^2 = c^2`).

Explanation:

Given that the width is 14' and the height is 5', you can figure out that the diagonal measurement is `sqrt(221` by plugging those values into the equation.

`a^2 + b^2 = c^2`
`14^2+5^2=c^2`
`14^2+5^2=221`
`c^2=221`

Then, you just cancel out the "squared" part of "`c^2`" by taking the square root (`sqrt`) out (because they are exact opposites, so they cancel each other out, kind of like addition and subtraction)

`c^2`=221
`sqrt(` `c^2`=`sqrt221`
c=`sqrt221`

so you end up with `sqrt221'` as the diagonal measurement of the rectangle since it can no longer be simplified.
