~~~~~~~~~~~~~~



This exercise is for those amateurs who love convert inches to feet and vise versa.


<pre>
5 feet 10 inches = 5*12 + 10 inches = 60 + 10 inches = 70 inches.


To solve the problem, write a proportion


    {{{shadow/height}}} = {{{12/x}}} = {{{60/70}}}.


From the proportion, find  x = {{{(12*70)/60}}}= {{{(12*7)/6}}} = 2*7 = 14 feet.    <U>ANSWER</U>

Solved.
