# Perimeter and Circumference Worksheets

What is the Difference Between Perimeter & Circumference? The word perimeter is derived from the Greek word peri meaning around and metron, which means to measure. Hence, in geometry, the perimeter is defined as the boundary or the path that surrounds a geometrical shape or object. In simpler terms, the perimeter is also defined as the outline of a geometrical shape. When we find the perimeter of the shape, we typically find the total length of sides of any two-dimensional shape. Initially, students are taught to use rulers and thread to measure the perimeter of a shape. But as they start learning geometry, they are taught different formulas to find out the perimeter of the shape. For example, if you are given a rectangle of length 3 inches by 8 inches, to find the perimeter. We all know that the opposite sides a rectangle are of the same lengths so that we will have two sides of measurement 3 inches and two sides of measurements 8 inches. We will add these four lengths to calculate the perimeter of a rectangle. We will have 3 + 3 + 8 + 8 = 22 inches. We use the same approach to find out the perimeter of most polygons. But finding the perimeter of a circular figure is different. For circles, we find the circumference, which is the complete distance around a circle. We can find the circumference by using the formula: C = 2πr, Where π = 3.14116 and r is the radius of the circle.
