How to find the area of a rectangle?


Answer: A rectangle is a closed two dimensional quadrilateral structure with four right angles (90 degrees).  Opposite sides of a rectangle are parallel and of equal length. Usually, the length of longer sides is called length of a rectangle and the length of shorter sides is called width/breadth of a rectangle.
Area of the rectangle is calculated by multiplying the length and width of the rectangle. For example, If the length of the rectangle is l and the width of the rectangle is w then area of the rectangle = (l x w).
If all sides of a rectangle are of equal length then it is called a square. Thus, square is a special case of a rectangle.
