All of the right triangles are similar.
.. (long side)/(short side) = 20/x = x/5
.. x^2 = 100 . . . . . . . . "cross multiply"
.. x = √100
.. x = 10
_____
The geometric mean of "a" and "b" is √(ab). x is the geometric mean of 20 and 5, the segments of the hypotenuse of the larger right triangle.
12+28+40+12=52
Perimiter =52ft
Yards=3 feet
52ft/3 is about 17.34yards
Now multiply yards by cost
17.34 x 15=260$
It costs 260 for titles to be put around the pool
