If your teacher wants to put a wallpaper border around the classroom where the ceiling meets the walls. And the class size is 36 x 42 it’s PERIMETER so the answer is 156

Answer 2

156

Explanation:

You would want to know the perimeter of the classroom. To get the perimeter, you need to know the width and the length of the classroom. Since the classroom area is 36*42, that means all you need to do is add 36 and 42 together, then time it by 2. 36+42=78 78*2=156
