It is a distance around a shape, example: Say I have a square in my hands well...you should know that a square has equal sides, right? Each side of that square I have is 4 …centimeters so all you do is add up all the sides. Like....4cm+4cm+4cm+4cm=16cm.That is what the perimeter is of THIS square! So basically it's the sum of all the sides of a shape. (MORE)

Perimeter is the distance around a object. Example: I have a square. One of the four sides of the square is 4 meters. To find the perimeter of polygon, you add all the lengt…hs together. In this case, you would add 4+4+4+4 (or simply 4x4). The perimeter of this square is 16 meters. (MORE)

Example 1: | Find the perimeter of a triangle with sides measuring 5 centimeters, 9 centimeters and 11 centimeters. / Solution: … | P = 5 cm + 9 cm + 11 cm = 25 cm / / Example 2: | A rectangle has a length of 8 centimeters and a width of 3 centimeters. Find the perimeter. / / Solution 1: | P = 8 cm + 8cm + 3 cm + 3 cm = 22 cm / Solution 2: P = 2(8 cm) + 2(3 cm) = 16 cm + 6 cm = 22 cm / / / In Example 2, the second solution is more commonly used. In fact, in mathematics, we commonly use the following formula for perimeter of a rectangle: , where is the perimeter, is the length and is the width. / / In the next few examples, we will find the perimeter of other polygons. / / / Example 3: | Find the perimeter of a square with each side measuring 2 inches. / Solution: | = 2 in + 2 in + 2 in + 2 in = 8 in / / Example 4: | Find the perimeter of an equilateral triangle with each side measuring 4 centimeters. / Solution: | = 4 cm + 4 cm + 4 cm = 12 cm / / / A square and an equilateral triangle are both examples of regular polygons. Another method for finding the perimeter of a regular polygon is to multiply the number of sides by the length of one side. Let's revisit Examples 3 and 4 using this second method. / / / Example 3: | Find the perimeter of a square with each side measuring 2 inches. / Solution: | This regular polygon has 4 sides, each with a length of 2 inches. Thus we get: / = 4(2 in) = 8 in / / Example 4: | Find the perimeter of an equilateral triangle with each side measuring 4 centimeters. / Solution: | This regular polygon has 3 sides, each with a length of 4 centimeters. Thus we get: / = 3(4 cm) = 12 cm / / Example 5: | Find the perimeter of a regular pentagon with each side measuring 3 inches. / Solution: | = 5(3 in) = 15 in / / Example 6: | The perimeter of a regular hexagon is 18 centimeters. How long is one side? / Solution: | = 18 cm / | Let represent the length of one side. A regular hexagon has 6 sides, so we can divide the perimeter by 6 to get the length of one side (). / = 18 cm รท 6 / = 3 cm / / / Summary: To find the perimeter of a polygon, take the sum of the length of each side. The formula for perimeter of a rectangle is: . To find the perimeter of a regular polygon, multiply the number of sides by the length of one side. (MORE)

Add all of the sides together.

That depends on exactly what you want to 'do' to it or with it. Do you want to calculate it ? Spell it ? Define it ? Walk around it ? Send it in Morse Code ? The perimeter… of an area or object is the total distance around its boundary. Measure each side with a ruler, yardstick, tape measure, etc. Then add all of these numbers together, and you have the perimeter. (MORE)
