How to Find Area and Perimeter of a Rectangle with Easy Examples
FAQs on Rectangle Area and Perimeter Practice for Grade 3
1. What is the formula for rectangle area and perimeter for Class 3?
The standard formulas used in Class 3 maths to calculate the area and perimeter of a rectangle are straightforward. These formulas help students solve basic geometry problems using the rectangle's length and breadth.
- Area of a rectangle formula: Length × Breadth (or L × B)
- Perimeter of a rectangle formula: 2 × (Length + Breadth) or 2 × (L + B)
This practice worksheet helps students apply these formulas with various examples.
2. What is the perimeter and area of a rectangle?
The perimeter and area are two fundamental measurements of a rectangle. While both use the rectangle's sides for calculation, they measure different properties of the shape.
- The perimeter is the total distance around the outside boundary of the rectangle. It is like measuring the length of a fence needed to enclose a field.
- The area is the total space or surface covered inside the boundaries of the rectangle. It is like measuring the amount of carpet needed to cover a floor.
3. How do you find the perimeter of a rectangle in 3rd grade?
To find the perimeter of a rectangle in 3rd grade, you need to add the lengths of all four sides. A simpler way is to use the standard formula which makes the calculation faster.
- First, identify the length (L) and the breadth (B) of the rectangle.
- Next, add the length and breadth together.
- Finally, multiply the sum by 2. The formula is: Perimeter = 2 × (Length + Breadth).
4. How can I use this Class 3 Maths Rectangle Area Perimeter worksheet at home?

5. How do you solve rectangle area and perimeter word problems?
Solving word problems for a rectangle's area and perimeter involves a few simple steps. This worksheet provides several word problems for practice.
- Read the problem carefully: Understand what is being asked—to find the area or the perimeter.
- Identify the given values: Note down the length and breadth from the question.
- Choose the correct formula: Use Area = L × B if the question asks for the space inside, or Perimeter = 2 × (L + B) if it asks for the boundary length.
- Calculate and write the answer: Solve the equation and remember to include the correct measurement units (e.g., cm, m, sq. cm, sq. m).
6. Is this worksheet printable and does it come with answers?
Yes, this Class 3 Maths worksheet is designed for easy use both online and offline. It is available as a free PDF printable worksheet that includes a complete answer key.
- Printable Format: You can easily download the worksheet as a PDF file and print it for your child to solve on paper.
- Answer Key Included: A detailed answer key is provided at the end of the worksheet, making it easy for parents and teachers to check the solutions.
7. What is the difference between the area and perimeter of a rectangle?
The key difference between area and perimeter is what they measure. Perimeter measures the length of the outer boundary, while area measures the total surface the shape covers.
- Perimeter: Measures the distance around a shape. Its unit is a unit of length (e.g., cm, m).
- Area: Measures the space inside a shape. Its unit is a square unit (e.g., sq. cm, sq. m).
For a rectangular park, the length of the fence around it is its perimeter, and the grass covering the ground inside is its area.
8. How can you find the area of a rectangle by counting squares?
For young learners in Grade 3, finding the area of a rectangle by counting squares is a great visual method. This approach helps build a strong foundational understanding of what area represents.
- A rectangle is drawn on a grid of unit squares (e.g., 1cm by 1cm squares).
- To find the area, you simply count the total number of these squares that are inside the rectangle.
- The final count gives the area in square units (e.g., 12 square cm).
9. What skills are built by this rectangle area and perimeter activity?
