Question

what is the area of a quadilateral with coordinates A(5,2) B(1,2), C(3,7) D(7,7)

Answer 1

Answer:

first you have to divide the quadrilateral into two triangles...then you have to lable the quad with the given points ...after that u will get two triangles

now u have to apply area formula on both the triangles and add the result

explanation-

formula is -

A= 1/2 {X1(y2-y3)+ x2(y3-y1)+x3(y1-y2)}

After applying this on both the triangles

add both the ans

and u will get the result
