What is rectangle in math ?
The word rectangle comes from the Latin rectangulus, which is a combination of rectus and angulus. A so-called crossed rectangle is a crossed quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals. It is a special case of an antiparallelogram, and its angles are not right angles. Like the cube, the rectangle is one of the most well-known quadrilaterals. It is defined as having all four interior angles of 90 degrees (right angles).
Rectangle area formula
The length of 2 adjacent sides are multiplied to evaluate the area of a rectangle.
Area of rectangle = width x length
How to calculate the diagonal of a rectangle ?
If you know the width and height of a square, you can calculate its diagonal. The diagonal is calculated by taking the square root of the distance squared plus the height squared.
Diagonal of rectangle = √( l2 + w2 )
How to find perimeter of a rectangle ?
