A boy 1.4 m tall casts a shadow 1.2 m long at the time when building casts a shadow 5.4 m long. The height of the building is

• Cross multiply and solve for x.
  1.4/1.2 = x/5.4
  solving this we get
  x = 6.3 m

• 1.4/1.2=L/5.4
  L=6.3

• 6.3
  
  
  tan x = 1.4 / 1.2 ------ eq 1
  tan x = H / 5.4 ------ eq 2
  
  using 1 and 2
  
  1.4/1.2 = H/5.4
  
  H= (1.4 * 5.4)/1.2
  H=6.3
