Step 1
Find the length of the side PQ
[tex]\begin{gathered} The\text{ coordinate of the point P is \lparen3,10\rparen} \\ The\text{ coordinate of the point Q is \lparen8,10\rparen} \end{gathered}[/tex]
Step 2
Find the length of PQ
[tex]\begin{gathered} Distance\text{ between two points} \\ D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ PQ=\sqrt{(8-3)^2+(10-10)^2} \\ PQ=\sqrt{25}=5 \end{gathered}[/tex]
Step 3
Part B
Draw the fountain since all sides are of the same length. A Hexagon has 6 sides. Therefore the perimeter will be;
[tex]\begin{gathered} 5+5+5+5+5+5=30 \\ or \\ 6\times5=30 \end{gathered}[/tex]
Answer;
[tex]Perimeter=30\text{ units}[/tex]
