a building 11m height a shadow length 23.1 then height of the building which casts the shadow of length 14.7 under smaller conditions will be

• 23.1 : 14.7 =11 : X
  X= 7

  Height of building casting shadow of length 14.7= 14.7*(11/23.1) =7
• 8 years agoHelpfull: Yes(19) No(2)
• 11m------23.1
  ??? ?-------14.7
  
  by cross multiplying :14.7*11/23.1=7.3

• 11 ---- 23.1
  x ---- 14.7
  x=7

• 11*14.7/23.7
• 7 years agoHelpfull: Yes(0) No(2)
• 23.1 : 14.7= 11 : X
  (i.e.,) 23.1/14.7 = 11/X
  Now cross myltiply, (23.1) * X = 11* 14.7
  (23.1) * X = 161.7
  X = 161.7/23.1
  X = 1617/231
  X = 7

• 7
  23.1:14.7=11:x
  23.1*x=11*14.7
  x=(11*14.7)/23.1
  x=7

• tan x = 11 /23.1
  tan x = a/14.7
  equate above two equations :
  i.e
  
  11/23.1 = a/14.7
  a = (11*14.7)/23.1 = 7m

• 7m. let req ht of the building be h then h/11 = 14.7/23.1
