### Grade 4 - Mathematics12.9 Perimeter of a Rectangle

 The perimeter of a rectangle is the distance around the outside of the rectangle. A rectangle has four sides with opposite sides equal. If l = length of the rectangle and w = width of the rectangle Perimeter = l + w + l + w = 2l + 2w = 2 (l + w) Perimeter = 2(l + w) units Example: What is the perimeter of a rectangle with length 8 cm and width 5 cm? Perimeter = 2(l+b) Perimeter = 2(8+5) Answer: 26 cm Directions: Answer the following questions. Also write at least five examples of your own.
