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?
Solution:
We have quadrilateral ABCD with
. AB=9 m. BC=12 m, CD=5 m and AD=8 m.
Using Pythagoras theorem on
, we get
m
Area of
base
height
(1)
Semi-perimeter of
m
Using Heron’s formula, Area of
(2)
Area of quadrilateral ABCD =area of
+ area of
Using (1) and (2) in the above equation, we get
Area of quadrilateral ABCD
