Area of Rectangle: Formula, Units, How to Calculate Area?

Area of Rectangle: The area of a rectangle is an important concept in geometry. A rectangle is a four-sided shape with opposite sides that are equal in length and four right angles.

To find the area of a rectangle, you simply multiply the length by the width. This formula is easy to use and is applied in many real-life situations, such as finding the area of a room, a piece of land, or a screen.

The area of rectangle tells us how much space the rectangle covers. This study notes article will provide an overview of how to calculate the area of a rectangle, using the formula length × width. It will also explore its applications and other key facts about rectangles.

Knowing how to calculate the area of rectangle is helpful for students as they continue learning about shapes and geometry. Study notes on the Area of Rectangle formula, how to calculate, and more are provided below.

What is the Area of Rectangle?

Area of a rectangle is a measure of the amount of space enclosed within its four sides. The area of a rectangle tells us how much space is inside it or the amount of surface it covers. To find the area, we need to know two measurements: the length and the width of the rectangle.

The length is the longer side, and the width is the shorter side of the rectangle. To calculate the area, we multiply the length by the width. The formula for the Area of a Rectangle:

Rectangle area formula = Length × Width 

• Length: The longer side of the rectangle
• Width: The shorter side of the rectangle

For example, if the length of the rectangle is 5 meters and the width is 3 meters, the area would be:

Area = 5 meters × 3 meters = 15 square meters

The unit of area will always be in square units (like square meters or square feet), depending on the units used for length and width. It is important to ensure that both the length and width are in the same unit before multiplying them.

Area of Rectangle Formula

The area of a rectangle is defined as the amount of space it occupies within its boundaries. To calculate this area, the formula:

Area = Length × Width

Units of Area of Rectangle

The units used to measure the area of a rectangle depend on the units used for the length and width. When calculating the area, it's important to use the same unit of measurement for both the length and the width.

Here are the common units of area:

• Square Centimeters (cm²) : Used when the length and width are measured in centimeters .
• Square Meters (m²) : Used when the length and width are measured in meters .
• Square Feet (ft²) : Used when the length and width are measured in feet .

How to Calculate Area of Rectangle?

Let's learn Find the area of rectangle for better understanding. Calculating the area of a rectangle is simple when you follow these steps:

Area = Length × Width

If the length is 8 meters and the width is 5 meters:

Area = 8 meters × 5 meters = 40 square meters

If the length is 12 inches and the width is 6 inches:

Area = 12 inches × 6inches = 72 square inches

By following these simple steps, you can easily calculate the area of any rectangle!

Examples of Area of Rectangle

Example 1:

A rectangular garden has a length of 12 meters and a width of 8 meters. What is the area of the garden?

Solution:

 The formula of area of rectangle to calculate the area of a rectangle is:

Area = Length × Width

Area = 12m × 8m = 96square meters

So, the area of the garden is 96 square meters .

Example 2:

A rectangular swimming pool is 25 feet long and 15 feet wide. What is the area of the pool's surface?

Solution:

 Using the rectangle area formula:

Area = Length × Width

Area =  25 ft × 15 ft = 375square feet

So, the area of the swimming pool's surface is 375 square feet .
