Question

the sides of a quadrilateral field taken in order are 5, 12 , 14 meters respectively, and the angle contained by the first two sides is a right angle. find its area​

Answer 1

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 m^2

The sides of a quadrilateral taken in order are 5,12,14 and 15 meters respectively.
