Rectangle Area Calculator

How to use the rectangle area calculator

The rectangle area calculator is an essential tool for students, teachers, architects, and engineers who need to calculate the area of rectangular surfaces. This calculator uses the basic geometry formula to calculate the area by multiplying width by height.

1. Accurately measure the rectangle dimensions: width and height
2. Enter the obtained values in the corresponding fields, using meters as the unit of measurement
3. Make sure to use a period (.) as the decimal separator if needed
4. Click the 'Calculate' button to get the result in square meters and hectares
5. Use the share or print buttons to save or send the result

Formula for calculating rectangle area

The calculation of a rectangle area is performed using a simple formula that multiplies width by height. This is one of the most basic and important formulas in geometry.

This formula considers that:

• Width is the measurement of one side of the rectangle
• Height is the measurement of the side perpendicular to the width
• The multiplication of these measurements provides the total area of the rectangle

Practical calculation examples

For better understanding, let's analyze some practical examples of area calculation:

• Rectangle with width of 5m and height of 3m. Area = 5 × 3 = 15m²
• Rectangle with width of 10m and height of 8m. Area = 10 × 8 = 80m²
• Rectangle with width of 25m and height of 40m. Area = 25 × 40 = 1,000m²
