2.25 kilometers on the ground is represented by 9cm on the map
According to the question, the scale on the map is in the ratio 1 : 25000
That is the length on the map = length of the ground
1cm = 25000 cm
1 cm = 25000/100000 km
1 cm = 0.25 km
Now we have to find the length of the ground in kilometres which is represented by 9cm on the map
That is we have to find the ratio, 9cm : x km
As from above, we know that,
1cm = 0.25 km
9 cm = 0.25*9 km
= 2.25 km
Hence 2.25 km on the ground is represented by 9 cm on the map
