Answers:
1.
The perimeter of the pentagon is the sum of the length of all sides of a pentagon. For a regular pentagon, the perimeter is 5 X side.
2.
Side (a) = 10 units
P = 5a ⇒ 5 × 10 = 50 units
Therefore, the perimeter of the pentagon is 50 units.
3.
Perimeter = sum of all its sides = 13 + 13 + 2 + 9 + 8 = 45m
Therefore, the perimeter of the pentagon is 45m.
4.
Perimeter = sum of all its sides = 5 + 4 + 7 + 3 + 6 = 25 units.
5.
Perimeter = sum of all its sides = 9 + 7 + 10 + 10 + 15 = 51cm
Therefore, the perimeter of the pentagon is 51cm.
6.
a) True, perimeter of a pentagon is the sum of the length of all sides of pentagon.
b) False, if the length of the side of a regular pentagon is 4 units, then the perimeter of that pentagon will be 20 units.
7. Side (a) = 3 units.
Perimeter = 5a = 5 × 3 = 15 units.
Therefore, the perimeter of the pentagon is 15 units.
8.
Side (a) = 7 units.
Perimeter = 5a = 5 × 7 = 35 units.
Therefore, the perimeter of the pentagon is 35 units.
9.
Perimeter = sum of all its sides = 3 + 7 + 8 + 9 + 6 = 33 units.
10.
Perimeter = sum of all its sides = 5 + 5 + 8 + 8 + 4 = 30cm
Therefore, the perimeter of the pentagon is 30cm.
11.
Side (a) = 10cm
P = 5a ⇒ 5 × 10 = 50cm
Therefore, the perimeter of the pentagon is 50cm.
12.
The perimeter of the pentagon = sum of its sides.
13.
Perimeter = sum of all its sides = 1 + 2 + 3 + 4 + 5 = 15 units.
Therefore, the perimeter of the pentagon is 15 units.
14.
Side (a) = 2 units
P = 5a ⇒ 5 × 2 = 10 units
Therefore, the perimeter of the pentagon is 10 units.
15.
Perimeter = sum of all its sides = 9 + 8 + 6 + 12 + 5 = 40 units
Therefore, the perimeter of the pentagon is 40 units.

FAQs on Perimeter Of Pentagon Worksheet Practice And Solutions
1. What is the perimeter of a pentagon?
The perimeter of a pentagon is the total length of all its five sides added together. In simple terms, you find the perimeter by summing the lengths of each side.
- For any pentagon: Perimeter = side₁ + side₂ + side₃ + side₄ + side₅
- The units are always linear units (cm, m, inches, etc.).
2. What is the formula for the perimeter of a regular pentagon?
The formula for the perimeter of a regular pentagon is P = 5 × s, where s is the length of one side.
- A regular pentagon has five equal sides.
- Multiply the length of one side by 5.
- Example: If one side is 6 cm, then P = 5 × 6 = 30 cm.
3. How do you calculate the perimeter of an irregular pentagon?
To calculate the perimeter of an irregular pentagon, add the lengths of all five unequal sides.
- Step 1: Measure or identify each side length.
- Step 2: Add them together.
- Example: 4 cm + 5 cm + 6 cm + 3 cm + 7 cm = 25 cm.
4. Can you give an example of finding the perimeter of a pentagon?
Yes, you can find the perimeter of a pentagon by adding its sides or using P = 5 × s for a regular pentagon.
- Example (regular): Side = 8 m
- P = 5 × 8 = 40 m
- Example (irregular): 5 m + 7 m + 6 m + 4 m + 8 m = 30 m
5. How do you find the side length of a regular pentagon if the perimeter is given?
To find the side length of a regular pentagon, divide the perimeter by 5. The formula is s = P ÷ 5.
- Example: If P = 45 cm
- s = 45 ÷ 5 = 9 cm
6. What units are used for the perimeter of a pentagon?
The perimeter of a pentagon is measured in linear units such as centimeters, meters, inches, or feet.
- If sides are in cm, the perimeter is in cm.
- If sides are in meters, the perimeter is in meters.
7. What is the difference between area and perimeter of a pentagon?
The perimeter of a pentagon is the total distance around it, while the area is the space inside it.
- Perimeter uses linear units (cm, m).
- Area uses square units (cm², m²).
- Perimeter formula (regular): P = 5 × s
8. Why do you multiply by 5 in a regular pentagon perimeter formula?
You multiply by 5 because a regular pentagon has five equal sides. The formula P = 5 × s works since all sides are the same length.
- Number of sides in a pentagon = 5
- Each side has equal length in a regular pentagon
9. How do you find the perimeter of a pentagon on a worksheet with missing sides?
To find the perimeter with missing sides, first calculate the missing length, then add all five sides together.
- Use given information (like equal sides or algebraic expressions).
- Example: If four sides are 5 cm each and one side is missing in a regular pentagon, then all sides are 5 cm.
- P = 5 × 5 = 25 cm
10. What are common mistakes when finding the perimeter of a pentagon?
Common mistakes when finding the perimeter of a pentagon include forgetting to add all five sides or confusing perimeter with area.
- Adding only four sides instead of five
- Using square units instead of linear units
- Using P = 5 × s for an irregular pentagon
