Understanding Rectangles: Length, Width, and Diagonal

A rectangle is a type of quadrilateral that has both opposing sides and diagonals that intersect each other. Unlike squares, which have all four sides equal in length, rectangles do not have equal-length sides. However, they do have two pairs of opposite angles that are equal.

The word 'rectangle' originates from the Latin words 'rectus,' meaning 'right' or 'straight,' and 'angulus,' meaning 'angle.' This unique combination of properties makes a rectangle distinct from other types of quadrilaterals.

A rectangle can be described as an equiangular quadrilateral, with all its angles equal to 90 degrees. Alternatively, it is also known as a parallelogram with right angles. In Euclidean plane geometry, a rectangle is defined as a quadrilateral with four right angles.

If you need to calculate the area or perimeter of a rectangle, this simple calculator can do it for you in seconds. Simply enter the length and width (or diagonal) of the rectangle, and we'll provide you with the values of P (perimeter) and A (area).

In everyday life, rectangles are all around us. We find them in carpets, parcels, TV screens, rectangular pools, windows, and many other objects. Understanding how to calculate their area and perimeter can be useful for various purposes.
