To measure hatched area in Fig. 1 Google Earth distance measurement has been used.

• All measurements repeated three times and averaged to minimize the error.
• Google Earth distance measurement tool does all measurement as level plane. This measurement is not accurate for inclined planes like roof.
• to minimize the error angle of the roof was measured and considered in calculations (Fig. 2).
• Top right and left red hatched area in Fig. 1 considered as triangles
• Bottom right and left red hatched area in Fig.1 each estimated to a half circle

Area calculation of top right and left triangles red hatched in Fig. 1[edit | edit source]

1. top left:
   • base= 63 m
   • leveled length (Google Earth)= 31 m
   • inclined length (considering 45 degree angled) = 43.84 m
   • Top left area= (63 m)*(43.84 m)/2 = 1381 m^2

1. top right
   • base= 45.2 m
   • leveled length (Google Earth)= 27 m
   • inclined length (45 degrees) = 38.18 m
   • Top right area= (45.2 m)*(38.18 m)/2= 863 m^2

Area calculation of bottom right and left half circles red hatched in Fig. 1[edit | edit source]

1. bottom left
   • diameter=30 m
   • half circle area= (pi*15^2)/2=350 m^2

1. bottom right
   • diameter=39 m
   • half circle area= (pi*19.5^2)/2=597 m^2

Total red hatched area in Fig.1[edit | edit source]

Total area= 1381 + 863 + 350 + 597 = 3191 (m^2)
