An estate is drawn to scale on a grid of 1 cm squares with a total area of 35 cm2 .If the actual area of the estate is 560 hectares, calculate the linear scale of the map.

  

Answers


Davis
Actual area = 560 ha = 560 x 108 cm2
Area of the map = 35 cm2
Area scale factor =(560 x 108)/35
= 16 x 108
Linear scale factor = square root of area scale factor.
Linear scale factor = square rt of 16 x 108
= 4 x 104
Hence, scale of map is
1: 40000.
