PowerPoint Presentation:

What do you know about the sides of rectangles Rectangles have 2 long sides that are the same length and 2 short sides that are the same length.

Finding Perimeter:

Finding Perimeter P = 14 9 What is perimeter? How do you find the perimeter of a shape? Remember the P in perimeter reminds you to “plus”! P = S + S + S + S P = 9 + 5 + 9 + 5 Find the perimeter of this shape. 5 If this side is 9, then we know the opposite side is _____ If that side is 5, then we know the opposite side is _____ If you only add the 9 and the 5 together then you are only finding half of the perimeter.
