Answer:

  • 19.25 feet

----------------------

We have got two similar triangles formed by casing a shadow.

Set up equal ratios for corresponding sides of the triangles:

  • x/5.5 = 14/4, where x- height of the building

Multiply both sides by 5.5 to find the value of x:

  • x = 14*5.5/4
  • x = 19.25
