उत्तर
To find the area by the grid square method: The grid square on toposheet measures 2 cm × 2 cm., or 1 km., × 1 km., since 2 cm., is equal to 1 km. Therefore, the area of each square is 1 sq. km. To find particular area on a topographical map:
No .of. complete squares : 4 = 4.0 sq.km
No.of 1/2 squares : 2 = 1.0 sq. km
No.of 2/3 squares : 5 = 3.3 sq.km
No.of 1/3 squares : 4 = 1.3 sq .km
__9.6 sq.km. ___
Note the number of complete grid square within the area and the number of squares lying within the area are not complete.
(i) Square covered half are taken as 1 /2 squares.
(ii) Square covered more than half are taken as 2/3 squares.
(iii) Square covered less than half are taken as 1/3 squares.
Add all the squares thus, the area which has to be found out is calculated.
