The area of the quadrilateral is 39.84 sq.units.
A quadrilateral is a polygon with four sides.
The quadrilateral ABCD is divided into 2 triangles by its diagonal
The area of Quadrilateral will be equal to the sum of the area of tho scalene triangles
The area of a scalene triangle is given by
[tex]\rm A = \sqrt{s (s-a)(s-b)(s-c)[/tex]
s is the semi perimeter = (a+b+c)/2
The sides of the Triangle ADC is 3.54, 17.29, 17.21
and The sides of the Triangle ABD is 7.84, 17.29, 9.59
s for ADC = (3.54+17.29+17.21)/2 = 19.02
s for ABD = 17.36
A for Triangle ADC is = 30.36
A for Triangle ABD is= 9.48
The total area of the quadrilateral is 30.36+ 9.48 = 39.84
