area of rectangle =l×b
36×24.5
882 m square
then
area of 2 semicircle=2×1\2 ×24.5×24.5
600.25 m square
then total area of ground =882+600.25=1482.25 m square
36×24.5
882 m square
then
area of 2 semicircle=2×1\2 ×24.5×24.5
600.25 m square
then total area of ground =882+600.25=1482.25 m square

heya frnd!!!
here is Ur answer>>>
area of rectangular part=l×b
=36×24.5
=882m²
radius for the semicircle part=24.5/2
=12.25m
area of both semicircle=πr²
=(22/7×12.5×12.5)
=3437.5/7m²
total area=882+3437.5/7
=6174+3437.5/7
=9611/7
=1373m²
hope this is the right ans and also helps you...
