How to Find the Perimeter of a Rectangle for Class 3 Students
FAQs on Perimeter of a Rectangle – Class 3 Maths Worksheet
1. How do you find the perimeter of a rectangle for Class 3?
Finding the perimeter of a rectangle for Class 3 students involves measuring the total distance around its boundary. You can do this by adding all four sides or by using a simple formula.
- First, identify the length (L) and the breadth (B) of the rectangle.
- Add the length and breadth together: (L + B).
- Multiply this sum by 2, because a rectangle has two equal lengths and two equal breadths.
- The formula is: Perimeter = 2 x (Length + Breadth).
- Always remember to write the answer with the correct unit, like cm or m.
2. What is the difference between the area and perimeter of a rectangle?
The main difference is that perimeter is the length of the boundary of a shape, while area is the amount of space it covers. For a Grade 3 student, think of it like this:
- Perimeter: This is like walking around the edges of a park. It is the total length of the path. It is measured in units like centimetres (cm) or metres (m).
- Area: This is like the grass inside the park. It is the total surface the park covers. It is measured in square units like square centimetres (sq. cm) or square metres (sq. m).
3. What is the perimeter of a rectangle whose length is 10 cm and breadth is 5 cm?
To find the perimeter of a rectangle with a length of 10 cm and a breadth of 5 cm, you use the perimeter formula P = 2 x (length + breadth). Here are the steps:
- Step 1: Add the length and breadth: 10 cm + 5 cm = 15 cm.
- Step 2: Multiply the sum by 2: 2 x 15 cm = 30 cm.
- Therefore, the perimeter of the rectangle is 30 cm. This is a typical example found in Class 3 maths worksheets.
