Maria's classroom is 22 ft long and 25 ft wide. How much paper is needed to make a border around the entire classroom?

94 ft of paper

Step-by-step explanation:

This is asking for the border, or, the perimeter of the classroom. You simply add all sides together.

You multiply each side by two as to make up for the missing sides of the classroom.

22 x 2 + 25 x 2

or

22 + 22 + 25 + 25

44 + 50

94 ft.
