so its 156?

mathstudent55 · Answer

The perimeter of a polygon is the sum of the lengths of all sides of the polygon.

In the rectangular room, there are two sides 13 ft long, and two sides 12 ft long.
Add 13 ft + 13 ft + 12 ft + 12 ft to get your answer.

so its 50?

mathstudent55 · Answer

When you multiply the length and the width, you get the area. You don't want the area. Here you want the perimeter.

mathstudent55 · Answer

Correct. The answer is: 50 ft.
