A park, in the shape of a quadrilateral ABCD, has , AB = 9 m, BC = 12 m, CD = 5 m and AD = 8 m. How much area does it occupy?
We have quadrilateral ABCD with . AB=9 m. BC=12 m, CD=5 m and AD=8 m.
Using Pythagoras theorem on , we get
Area of base height
Semi-perimeter of m
Using Heron's formula, Area of
Area of quadrilateral ABCD =area of + area of
Using (1) and (2) in the above equation, we get
Area of quadrilateral ABCD
