Calculating Perimeter of Polygons

What does the perimeter of a polygon represent?

• The space inside the polygon

• The distance around the polygon

• The volume of the polygon

• The number of sides of the polygon

Why is it important to distinguish between area and perimeter?

• They are both related to volume

• They are calculated the same way

• They represent different measurements

• They have the same units

Which of the following is a common mistake when calculating perimeter?

• Adding the side lengths incorrectly

• Ignoring the corners of the polygon

• Counting the area instead of the perimeter

• Confusing perimeter with volume

What is a key step in avoiding mistakes when calculating perimeter?

• Calculating the area first

• Ignoring the corners

• Counting all sides accurately

• Measuring the angles

What should you do if you confuse a side length with a diagonal?

• Ignore the diagonal

• Measure the diagonal instead

• Ensure the side length stops at a corner

• Recalculate the area

How can you find the side lengths of a polygon?

• By calculating the area

• By counting the squares along each side

• By dividing the perimeter by the number of sides

• By measuring the angles

What is the first step in calculating the perimeter of a polygon?

• Divide the side lengths

• Add up the side lengths

• Subtract the side lengths

• Multiply the side lengths

In the example provided, what is the perimeter of the polygon?

• 18 units

• 24 units

• 20 units

• 22 units

What is the perimeter of the first polygon revisited in the lesson?

• 24 units

• 22 units

• 20 units

• 18 units

What is the final step in finding the perimeter of a polygon?

• Divide the total by the number of sides

• Subtract the smallest side length

• Add all the side lengths together

• Multiply the side lengths
