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
