The map given below shows a meandering river following a semi-circular path, along which two villages arelocated at A and B. The distance between A and B along the east-west direction in the map is 7 cm. What isthe length of the river between A and B in the ground?
Distance of river on ground = perimeter of semi circle
= ? x r = 3.14 x 3.5 = 11 cm
According to Scale = 11 x 50,000 cm = 5,50,000 cm or 5.5 km
