The diagram illustrating the given scenario is shown below
The height of the flagpole is represented by h. We can see that the figures are similar. Thus, the possible proportions that could be used to solve for the height of the flagpole is
h/60 = 5'6''/4'
We would convert 5 feet, 6 inches to feet. Recall,
1 foot = 12 inches
then, 6 inches would be 6/12 = 0.5 foot
The height of the woman is 5 feet + 0.5 foot = 5.5 feet
Thus, the required proportion is
h/60 = 5.5/4
