Calculate area of topo sheet in 1:50 000 scale,
Having following information as below-
No. of grids in Topo sheet -9
Area of one grid -18.50 x 17.10 cm
Solution: Given scale is 1:50000
OR
1cm: 50 000 cm
OR
1cm: 500 m
OR
1cm: 0.5km
2cm -1km
So that,
18.5 cm =9.25 km
17.10 cm=8.55 km
Area of the Grid- 9.25x8.55=79.087 = 79 sq.km.
Area of the one topo sheet 79 x 9=711 sq.km
