Question

How to calculate area of a quadrilateral?

Answer 1

There are some types of quadrilateral.To calculate the Area all have different formulas.Some of them are as follows:-
1.Rectangle :- Length x Breadth
2. Square:-(side)^2
3. Parralelogram:-Base x Altitude
4. Rhombus:- Diagonal 1 x diagonal 2.
5. Trapezium:- 1/2xsum of parallel side x Altitude.

Another method to calculate the Area of any quadrilateral is divide the quadrilateral in Triangles nd find the area of the Triangle

Hope this will help u

Hi !

Quadrilateral is a polygon with four sides. Examples of quadrilaterals are square , rectangle , rhombus , kite , trapezium , etc.

If the shape of the quadrilateral is not exactly as that of the quadrilaterals mentioned above , we can find its area by dividing the quadrilateral into two parts , which would give us two triangles . and by the formula to find the area of triangles , we can find the area of both the triangles and just add them together to find the area of the quadrilateral.

In case the shape if specified (square , rectangle.etc) , then we can use the following formulas :-
 
Square = side*side
Rectangle = length*breadth
Trapezium = 1/2(a+b)height
Rhombus = 1/2*diagonal1*diagonal2
