12.9 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
