area of tri.having base 16 and height 6=1/2×16×6=48m2
area. of tri. having base 4 and height 2= 1/2×2×4=4m2
area of tri.having base 14 and height 8=1/2×8×14=56m2
area of tri.having base 6 and height 4=1/2×6×4=12m2
now area of the shaded region =200-(48+4+56+12)
=200-120
=80 m2
hope this will be helpful.
