The sin <ABC means that AC/AB. So we know AB=34. AC/AB=8/17. So the length of AC is 16. cos<ABC means BC/AB. tan<ABC means AC/BC.
This football field has 36 squares. As each square's area is 1 m^2. So, total area is 36 m^2.
the area = 8×1 = 8 m^2( this portion is not shaded )
i.e, the area of shaded part will be (36-8) = 28 m^2.
