# Area of a Rectangle Calculator

Calculating the area of a rectangle is one of the basic topics in Geometry. One simply needs to know the length and breadth of the rectangle. In this calculator, the length and breadth is entered and the calculator can find the area instantly.

## Area of a rectangle formula

Area of a rectangle = length (l) x breadth (b)

## How to calculate the area of the rectangle?

Step 1: Enter the length of the triangle
Step 2: Enter the breadth of the triangle
Step 3: Click the Calculate button
Step 4: If you want to view the calculation then click on the Show Solution checkbox

On clicking the Convert button, the area of the rectangle will be shown in sq. units.

## Examples for the calculation of the area of the rectangle

### Calculate the area of the rectangle with a length of 5 units and breadth of 4 units

Area of rectangle = length (l) x breadth (b)
= 5 x 4
= 20 square units

### Calculate the area of the rectangle with a length of 8 units and a breadth of 4 units

Area of rectangle = length (l) x breadth (b)
= 10.5 x 21.4
= 224.7 square units

## What is a rectangle?

A rectangle is a geometric shape that has four sides, and all the interior angles are right angles (90 degrees). The opposite sides of a rectangle are equal in length, and the adjacent sides are perpendicular to each other. A rectangle can be described as a two-dimensional shape with a length (l) and a width (w).

## What is the area of a rectangle?

The area of a rectangle is the total amount of space that is enclosed by the rectangle. It is calculated by multiplying the length and width of the rectangle. The formula for calculating the area of a rectangle is:

Area = length x width

This formula can be applied to any rectangle, regardless of its size or orientation. The units of measurement for the area of a rectangle can vary, depending on the application. For example, the area of a rectangle in construction might be measured in square feet, while the area of a rectangle in mathematics might be measured in square units.

## How to calculate the area of a rectangle?

To calculate the area of a rectangle, you need to know the length and width of the rectangle. You can measure these values using a ruler, tape measure, or other measuring tools. Once you have the values, simply multiply the length and width together to get the area.

Here’s an example:

Suppose you have a rectangle with a length of 8 feet and a width of 4 feet. To find the area of this rectangle, you would use the formula:

Area = length x width Area = 8 ft x 4 ft Area = 32 square feet

So, the area of this rectangle is 32 square feet.
