See the fact file below for more information on the problems involving perimeters or alternatively, you can download our 31-page Problems Involving Perimeters worksheet pack to utilise within the classroom or home environment.

Key Facts & Information

DEFINITION

  • The perimeter of a shape is the distance or length that goes around it.
  • To find the perimeter of a shape, you have to do two things:
    • Start by knowing the length of each side.
    • Add the lengths of all the sides.

UNITS OF LENGTH

  • When measuring objects in the real world, always include a unit of length, so people will know the actual length of an object.
  • Miles and kilometers are used for really long distances.
  • Inches and centimeters are used for smaller objects.
  • Meters and feet are used for medium-sized spaces and objects.
  • It’s very important to use the correct unit of length when finding the perimeter. Say for example, you need to build a fence around your pool. When you measure its sides, you use only one unit of length.
  • When you know the unit of length for the perimeter, you know how many materials to get for building the fence.
  • To find the perimeter of a shape, add the lengths of all the sides.
    • 10 + 15 + 10 + 15 = 50
  • The perimeter of the swimming pool is 50 meters or 50 m.
  • Here’s another example. Pretend you’re baking and you’re using a square baking pan. Find its perimeter.
  • Given that the pan is a square, and we all know that a square has 4 equal sides, thus, the length of one side is same as the length of all the other three sides.
  • Since one side is 8 inches long, we can assume that the other sides are also 8 inches long.
  • Since we’re adding the same number 4 times, we can just multiply the length of one side by the total number of sides.
  • Therefore, the perimeter of the baking pan is 32 inches or 32 in.
  • PERIMETER OF A RECTANGLE
    • PERIMETER = length + width + length + width
      or
      PERIMETER = (2 x length ) + (2 x width)
  • PERIMETER OF A SQUARE
    • PERIMETER = length + length + length + length
      or
      PERIMETER = 4 x length

RELATIONSHIP BETWEEN AREAS AND PERIMETERS

  • Perimeter and area are two different things. How are they related?
  • Perimeter is the length or distance around a shape or space.
  • To find the perimeter, simply add the lengths of all the sides.
  • Area is the space taken up by a flat shape.
  • To find the area, multiply its width by its height.
