Surface Area of a Rectangle Calculator

This surface area of a rectangle calculator is the perfect tool for you to calculate the surface area of a rectangle from its length and width. In this article, we shall go over the surface area of a rectangle, its equation, how to find the surface area of a rectangle, and some frequently asked questions.

A rectangle is a closed figure with four sides, whose opposite sides are equal. Hence, two sides or dimensions are sufficient to describe a rectangle — its length (sometimes called height) and its width (sometimes called breadth).

The equation for the surface area of a rectangle is given by:

where:

• $\text{A}$ is the surface area of the rectangle;
• $\ell$ is the length of the rectangle. Usually, it refers to the longest side of the rectangle.
• $w$ is the width of the rectangle. Usually, it refers to the shortest side of the rectangle.

The SI units for area are $\text{m}^2$ or $\text{sq m}$ (square meters), and its imperial units are $\text{ft}^2$ or $\text{sq ft}$ (square feet). Always ensure that the length and width are expressed in the same units before using the surface area formula of a rectangle.

For example, a rectangle with $5 \text{ m}$ length and $2 \text{ m}$ breadth (or width) would have a surface area of $5 \times 2 = 10 \text{ m}^2$.

To find the surface area of a rectangle, you require its length and width:

1. Convert the length and width into the same unit. We must measure them both in the same unit. For example, if the length is 5 m, and width is 2 ft, convert both to either m or ft.
2. Multiply this length and width to obtain the area in corresponding units.
3. Double-check your answer using the surface area of a rectangle calculator.

This surface area of a rectangle calculator is simple to use:

1. Enter the length of the rectangle in its appropriate field. Ensure you've picked the suitable units.
2. Enter the width (or breadth) of the rectangle in its appropriate field. Again, ensure that you've picked the correct units.
3. This surface area of a rectangle will automatically find the surface area of the rectangle and display the result in the appropriate field.

So now you know how to find the area of a rectangle!
