Carly bedroom is 2 feet longer than its width. the perimeter is 44 feet. what is the length of her bedroom?

Simple,

writing an equation to find the sides,

x+2+x+2+x+x=44

4x+4=44

Subtract 4 from both sides, making the equation look like this,

4x=40

Divide by 4

x=10.

To check it, just plug it back into original equation.

10+2+10+2+10+10=44

It works. :)
