The sides of a qu

Answer :

Let consider a quadrilateral ABCD


In ∆ABC;


AC = = 13 m


AB = a = 5 m, BC = b = 12 m, AC = c = 13 m



Let a, b and c are the sides of triangle and s is


the semi-perimeter, then its area is given by:


A = where [Heron’s Formula]


= = 15


A1 =


A1 = = m2


In ∆ADC;


DA = a = 15 m, CD = b = 14 m, AC = c = 13 m


Let a, b and c are the sides of triangle and s is


the semi-perimeter, then its area is given by:


A = where


= = 21


A2 =


A2 = = m2


Therefore area of quadrilateral ABCD = A1 + A2 = 30+84 = 114 m2
