Using the points
A(8,4)
B(2,12)
C(12,36)
D(36,36)
E(26,10)
the distance formula sqrt (diff in x^2+diff in y^2)
AB is 10
BC is 26
CD is 24
DE is 26
EA is 6 sqrt(10)
This is 86+6 sqrt(10 feet)=104.97 or 105 feet.

from the graph:
A (8,4)
B(2,12)
C(12,36)
D(36,36)
E(26,10)
the length of each side is equal to distance between its endpoints
AB=sqrt%28%282-8%29%5E2%2B%2812-4%29%5E2%29=sqrt%2836%2B64%29=sqrt%28100%29=10
BC=sqrt%28%2812-2%29%5E2%2B%2836-12%29%5E2%29=sqrt%28100%2B576%29=sqrt%28676%29=26
CD=sqrt%28%2836-12%29%5E2%2B%2836-36%29%5E2%29=sqrt%28576%29=24
DE=sqrt%28%2836-26%29%5E2%2B%2836-10%29%5E2%29=sqrt%28100%2B676%29=27.86
EA=sqrt%28%2826-8%29%5E2%2B%2810-4%29%5E2%29=sqrt%28324%2B36%29=18.97
add all lengths together:
10%2B26%2B24%2B27.86%2B18.97=106.83=107
she need 107 feet of fencing

I think NEITHER of these 2 people's answers are correct. Since it's stated that each UNIT represents 1 foot, doesn't this mean that: 

A (8, 4)   ;   B (2, 12)  ;   C (12, 36)   ;   D (36, 36)   ;    E (26,10) is actually:

A (4, 2)   ;   B (1, 6)   ;   C (6, 18)    ;   D (18, 18)   ;    E (13, 5)
