## Rectangle Area Calculator

Type the length and width of the rectangle:

A rectangle is a quadrilateral with four right angles, opposite sides that are congruent, and opposite sides that are parallel. The area of a rectangle is the amount of space that is enclosed by its sides, and it is measured in square units.

To find the area of a rectangle, we need to know its length and width. The formula for the area of a rectangle is:

Area = Length x Width

Here, the length is the longer side of the rectangle, and the width is the shorter side.

For example, consider a rectangle with a length of 8 units and a width of 5 units. The area of this rectangle can be calculated as:

Area = 8 x 5 = 40 square units.

So, the area of this rectangle is 40 square units.

The area of a rectangle can also be calculated using other measurements, such as the perimeter or diagonal. For example, if the perimeter of a rectangle is known, the area can be calculated using the following formula:

Area = (Perimeter x Width)/2

Let’s take an example to illustrate this. Consider a rectangle with a perimeter of 26 units and a width of 4 units. To find the area of this rectangle, we can use the formula:

Area = (Perimeter x Width)/2 Area = (26 x 4)/2 Area = 52 square units

So, the area of this rectangle is 52 square units.

Another way to find the area of a rectangle is to use the Pythagorean theorem if the length and diagonal of the rectangle are known. The formula for the area of a rectangle using the diagonal is:

Area = (Diagonal x Width)/2

Let’s take an example to illustrate this. Consider a rectangle with a length of 5 units and a diagonal of 13 units. To find the area of this rectangle, we can use the formula:

Width = √(Diagonal^2 – Length^2) Width = √(13^2 – 5^2) Width = √(144) Width = 12

Now, we can use the formula for the area of a rectangle using the diagonal:

Area = (Diagonal x Width)/2 Area = (13 x 12)/2 Area = 78 square units

So, the area of this rectangle is 78 square units.

In summary, the area of a rectangle is the product of its length and width. It can also be calculated using other measurements such as the perimeter or diagonal.
