I had a bronchitis the past week, and I have no idea what to do with this problem, my teacher gave us two problems out of 28 from the upcoming quiz, and this is one of the two.

What the following absolute value using a piecewise function?

y=|x+5|+2

Express the area of a rectangle with a perimeter of 100 with 1 size as length is x.

Any help would be appreciate!
