AREA OF A QUADRILATERAL

-->
Today let us know on how to find the area of Quadrilateral.
A Quadrilateral is a polygon with four sides. The parts of a quadrilateral are its sides, its four angles, and its two Diagonals. The perimeter of a quadrilateral is the sum of the lengths of its sides.
The area of the quadrilateral can be found by dividing it into triangles and summing the areas of the triangles.
Let us know see some examples on how to calculate the area of a quadrilateral.
Example 1) Calculate the area of a rectangle with length 10cms and width 10cms.
Area of a square = Length * width
A = 1*w
A = 10*10
A = 100cm
Example 2) Calculate the area of a square with length of each side as 20cms.
Area of a square = s2
A = 202
A = 400cms
