Answer:
322.9 ft
Step-by-step explanation:
See attachment for the diagram
ro: radius of outer circle
ri: radius of inner circle
Length of inner railing= circumference of inner semi-circle+ twice of inner horizontal sides
Length of inner railing= ri+ 2×(70- ro)
= × 45/2+ 2×(70-65/2)
=145.71 ft
Lenth of outer railing= circumference of outer semi-circle+ twice of outer horizontal sides
= ro+ 2×(70- ro)
= × (65/2) + 2×(70-65/2)
=177.14ft
Total length of railing =177.14+145.71
= 322.85ft
