Area: Explanation and Study Guide
What is the concept of area?
Area is a measure of the size of a surface or a two-dimensional shape. It is the amount of space inside a shape, and is measured in square units. The most common units used to measure area are square inches, square feet, square meters, and square centimeters.
How is area calculated for different shapes?
The formula for calculating the area of different shapes are as follows:
- For a square or rectangle, the area is calculated using the formula: Area = length x width.
- For a triangle, the area is calculated using the formula: Area = (base x height) / 2.
- For a circle, the area is calculated using the formula: Area = π x (radius x radius), where π (pi) is a constant approximately equal to 3.14159.
How can I practice calculating area?
To practice calculating area, you can use the following study guide:
- Start by understanding the concept of area and the formula for calculating area for different shapes.
- Practice calculating the area of squares, rectangles, triangles, and circles using the respective formulas.
- Use real-life examples to apply the concept of area, such as calculating the area of a room, a piece of land, or a circular swimming pool.
- Work on word problems that involve finding the area of different shapes, as this will help you in applying the concept to real-world scenarios.
- Use online resources and math worksheets to further practice and reinforce your understanding of area.

Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
