Word Problems Involving Areas of Plane Figures - JSS3 Mathematics Lesson Note
These problems involve real-world scenarios where knowledge of area calculations is necessary. For example:
Example:
A circular swimming pool has a radius of 5 meters. What is the area of the pool?
To solve:
Use the formula for the area of a circle:
Area=𝜋𝑟^2
Substitute
𝑟=5 meters.
Area=𝜋×(5 m)2
Area =𝜋×25
Area=25𝜋
Area ≈ 78.54 square meters
