Answer 1

Solution given:

length [l]=20cm

breadth [b]=10cm

area of rectangle =l×b=20×10=200cm²

since 1cm=1000cm

than real area =200×1000²=200000000cm²

since

1 hectares =10000m²=10000×10000=100000000cm²

so

200000000cm²=2hectares

So,actual area of the piece of land in hectares is 2 hectares.
