  1. Perimeter The distance around the outside of a shape.

  2. The distance around the outside of a rectangle. Perimeter

  3. To find the perimeter you need to measure the length of each side of the rectangle. Perimeter then add them together.

  4. Measure each side of the triangle then add them together. Perimeter

  5. The distance around the outside of a circle. Distance across middle. Diameter Circumference Distance from middle to circumference. Radius

  6. The distance around the outside of a rectangle. length Perimeter width width length Perimeter = (2 x L) + (2 x W)

  7. Do you have to measure every side to find the perimeter of these shapes? Perimeter
