Answer
$4109ft$
Work Step by Step
Use the formula given to find the measurement of one wire for each height.
Short wire =$ \sqrt (200^{2}+(0.55\times200)^{2}) \approx 228.3$
Middle wire = $ \sqrt (400^{2}+(0.55\times400)^{2}) \approx 456.5$
Large wire = $ \sqrt (600^{2}+(0.55\times600)^{2}) \approx 684.8$
Each height has 3 wires so multiply each height by 3:
$228.3\times3 = 684.9$
$456\times3 = 1369.5$
$684.8\times3 =2054.4$
Add them all up:
$684.9+1369.5+2054.4=4108.8$
