Detailed Solution for BSF Sub Inspector (SI) Mock Test - 3 - Question 14

Calculation of Carpet Area:


  • Length of the building = 17.3m

  • Breadth of the building = 10.3m

  • Thickness of walls = 0.3m (applicable to all sides)

    •  

Calculating the Inner Dimensions:


  • Length of inner rectangle = Length of building - 2 * Thickness = 17.3m - 2 * 0.3m = 16.7m

  • Breadth of inner rectangle = Breadth of building - 2 * Thickness = 10.3m - 2 * 0.3m = 9.7m

    •  

Calculating Carpet Area:


  • Carpet Area = Length * Breadth = 16.7m * 9.7m = 162.19m2
