Rectangle Area Calculator
A rectangle area calculator is a tool that computes the area and perimeter of a rectangle based on its length and width. This simple geometric calculator helps in various applications where rectangular measurements are needed.
When to Use a Rectangle Area Calculator
This calculator is useful in several scenarios:
Home improvement projects to calculate flooring, painting, or wallpaper requirements
Construction and architectural planning to determine material quantities
Educational purposes to understand basic geometric concepts
How to Calculate
The calculations for a rectangle are based on two primary formulas:
Area of a Rectangle: A = Length × Width
Perimeter of a Rectangle: P = 2 × (Length + Width)
When using this calculator, you'll need to input:
Length of the rectangle
Width of the rectangle
