Question

Two sides of a triangular field are 120m
and 200m.If the angle between the sides is 68 degrees. find the
area of the field in hectares

Answer 1

Area of a triangle = (1/2)(ab)sinØ
where a and b are sides with Ø as the angle between them.
Your data is perfectly suited for that formula

Answer 2

1/2(120)(200)sin68
=11126.206m squared
