Practice problems of the perimeter - page 6 of 48
A perimeter is a closed path that encompasses, surrounds two dimensional shape. The perimeter is the distance around a shape. The perimeter of a circle or an ellipse is called its circumference. The word comes from the Greek perimetros from peri "around" and metron "measure".Number of problems found: 952
