So basically -3 x 16. Yeilds -48
To solve for the length of a perimeter, use
L = P/2﹣w
L = 66/2 - 7
L = 33 - 7
L = 26
The length is 26
The length of the wire is 37.15 ft
<u>Explanation:</u>
The figure is attached for the reference.
tan (71) = 
tan (36) = 
So,
tan(36) (36 + x) = y
tan(71) = 

Substituting x = 12.11 ft in equation 1:

Length of the wire, z = 
So,

Therefore, the length of the wire is 37.15 ft
