Answer:
Given that sides of quadrilateral are AB = 5 m, BC = 12 m, CD = 14 m and DA = 15 m AB = 5m, BC = 12m, CD = 14 m and DA = 15 m Join AC In ∆ABC By applying Pythagoras theorem. By using Heron’s formula Area of quadrilateral ABCD = area of ( ∆ABC) + Area of (∆ADC) = 30+84 = 114 m2Read more on Sarthaks.com - https://www.sarthaks.com/110477/the-sides-of-a-quadrilateral-taken-in-order-are-5-12-14-and-15-meters-respectively hope it's help you...
