plzz solve this question ..Q 2

Answer 1

"The Area of Quadrilateral ABCD in which AB = 3 cm, BC = 4 cm, CD = 4 cm, DA = 5 cm and AC = 5 cm

Area of Quadrilateral = Area of ΔABC + Area of ΔADC Area of ΔABC Area of triangle = √(s (s−a) (s−b) (s −c))

s is the semi-perimeter

a, b, c are the sides of the triangle

Here, , and a, b, c are the sides of the triangle

Here, a = 3 , b = 4, c = 5 S = ( + + )/2 Area of Δ ABC = √(( −)( −)( −))
