What's is the absolute value -18 degrees

The absolute value would be 18 !

The absolute value kind've serves as the opposite as a number, if you think of it in a way.
|-10| comes out to be 10. Think of it as in steps, your back 10 steps but you need to go 10 steps forward to get to 0, again. (into positive territory.) So 18 degrees.

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width
