s c a l e 1 : 40000 m e a n s

1 c m o n m a p = 40000 c m i n r e a l i t y

o r

1 c m o n m a p = 400 m i n r e a l i t y

o r

1 c m o n m a p = 0.4 k m i n r e a l i t y

o r

1 {c m}^{2} o n m a p = 0 . 4^{2} = 0.16 {k m}^{2} i n r e a l i t y

n o w t h e q u e s t i o n i s

x {c m}^{2} o n m a p = 170 {k m}^{2} i n r e a l i t y ?

\frac{x}{1} = \frac{170}{0.16}

\Rightarrow x = 170 / 0.16 = 1062.5 {c m}^{2}
