Rectangle Calculator

What is Rectangle Calculator

Our Rectangle Calculator is a tool designed to compute various rectangle properties. With this calculator, you can determine the area, perimeter, length of the diagonal, as well as the aspect ratio of a rectangle. It also allow to use different units when providing leanth and width values.

Area of a Rectangle

The area of a rectangle is calculated by multiplying the length and the width of the rectangle.

Formula: Area = length × width

Example: For a rectangle with a length of 5 cm and a width of 3 cm, the area is 15 cm².

Perimeter of a Rectangle

The perimeter of a rectangle is calculated by adding up all its sides.

Formula: Perimeter = 2 × (length + width)

Example: For a rectangle with a length of 5 cm and a width of 3 cm, the perimeter is 16 cm.

Diagonal of a Rectangle

The diagonal of a rectangle is calculated using the Pythagorean theorem.

Formula: Diagonal = √(length² + width²)

Example: For a rectangle with a length of 5 cm and a width of 3 cm, the diagonal is approximately 5.83 cm.

Aspect Ratio of a Rectangle

The aspect ratio of a rectangle is the ratio of its width to its length.

Formula: Aspect Ratio = width : length

Example: For a rectangle with a length of 5 cm and a width of 3 cm, the aspect ratio is 3:5.
