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?
