The Rectangle Area Calculator determines the area enclosed by a rectangle from its length and width. Area describes the amount of two-dimensional surface inside the shape and is commonly measured in square units.
Rectangle Area Formula
The formula is A = length Γ width. Both measurements must use compatible units before multiplication.
How to Use the Calculator
- Enter the rectangle's length.
- Enter its width.
- Use the same unit for both measurements.
- Calculate the area and review the square-unit result.
Example
A rectangle that is 12 meters long and 5 meters wide has an area of 12 Γ 5 = 60 square meters.
Area Versus Perimeter
Area and perimeter describe different properties. Area measures the surface inside the rectangle, while perimeter measures the total distance around its boundary. The perimeter formula is 2(length + width), so it should not be confused with the area calculation.
Unit Check
If length and width are entered in centimeters, the result is in square centimeters. Converting the dimensions before calculating can prevent inconsistent units.
