area of trapezium= 1/2*sum of ll sides *height
area of trap abcd=1/2*(55+45)*30
=1500
according to ASP sum of angles of a quad = 360
so some of all sectors = 360
because their radii are same they form a complete circle
area of circle = pie r square
=22/7*14*14
=616 m square
area of shaded region = area of trap-area of sectors
=1500-616
=884 metre square
