Solution
Draw a diagramatic representation of the question
Step 2
Add both heights to determine the height of the block including the tower antenna
[tex]\begin{gathered} \frac{1}{4}+4\frac{2}{3} \\ =\frac{1}{4}+\frac{14}{3} \\ =\frac{59}{12}\text{feet} \\ =4\frac{11}{12}\text{ f}eet \end{gathered}[/tex]
Hence the total height required = 59/12 feet or 4 11/12 feet approximately
