# Area of a rectangle calculator

Area of a Rectangle Calculator is an online tool that calculates the area of a rectangle with a given length and width. The amount of space enclosed within the boundaries of a rectangle is known as the area of that rectangle.

## What Is Area of a Rectangle Calculator?

Area of a Rectangle Calculator computes the area of a rectangle by taking the product of the length and the width. The number of unit squares that can be fit into a rectangle gives the measure of its area. To use the * area of a rectangle calculator*, enter the values in the input boxes.

## How Does Area of a Rectangle Calculator Work?

A rectangle is a special type of quadrilateral. Thus, it is a 2D closed figure with four sides, four angles, and four vertices. All the angles of a rectangle measure 90 degrees. The opposite sides of a rectangle are equal and parallel. Furthermore, as a rectangle has parallel sides, it can also be known as a parallelogram. Thus, we can say that all rectangles are parallelograms but all parallelograms are not rectangles. The length is the longer side of the rectangle while the width is the shorter side. Sometimes, the width is also known as the breadth of the rectangle. The steps to find the area of a rectangle are given as follows:

- Note down the length and width of the rectangle.
- Multiply the length by the width. This gives the area of the rectangle.
- Express the area in square units.

The formula to find the area of a rectangle is given as follows:

Area of a rectangle = length × width.

## Solved Examples on Area of a Rectangle

**Example 1:** Calculate the area of a rectangle with a length of 5 units and a width of 3 units. Verify the result using the area of a rectangle Calculator

**Solution:**

Area of a rectangle = length x width

= 5 units x 3 units

= 15 square units

The area of the rectangle is 15 square units.

**Example 2:** Calculate the area of a rectangle with a length of 7.2 units and a width of 5.5 units. Verify the result using the area of a rectangle Calculator

**Solution:**

Area of a rectangle = length x width

= 7.2 units x 5.5 units

= 39.6 square units

The area of the rectangle is 39.6 square units.

Now, use the calculator to find the area of rectangles with the following length and width:

- Length = 8 units and width = 15 units
- Length = 10.3 units and width = 8.2 units
