Question 1138999
.
<pre>

This problem is "<U>on proportions</U>".


If you have two objects (buildings, trees, persons, flagpoles) with the heights  {{{H[1]}}}  and  {{{H[2]}}},  

that cast shadows of the lengths {{{L[1]}}}  and  {{{L[2]}}}, respectively, these values are connected with a proportion


    {{{H[1]/L[1]}}} = {{{H[2]/L[2]}}}.


In your case,


    {{{136/34}}} = {{{x/1.5}}}.


From this proportion, find the unknown x, which is the man's height


    x = {{{(136*1.5)/34}}} = 6.


<U>ANSWER</U>.  The man is 6 ft tall.

Solved.
