Answer: 31.5938183883 units
Explanation:
Use the distance formula to calculate the perimeter for each side:
d = √((X2-X1)^2+(Y2-Y1)^2)
Example: Coordinates for T (1,11) and U (5,7)
Distance (d) = √(5 - 1)^2 + (7 - 11)^2
= √(4)^2 + (-4)^2
= √32
= 5.6568542494924
U (5,7) and Q (3,0)
Distance = 7.2801098892805
Q (3,0) and R (-3, 0)
Distance = 6
R (-3,0) and S (-3,7)
Distance = 7
S (-3,7) and T (1,11)
Distance = 5.6568542494924
After finding the distance, add the five distances together to get the perimeter:
5.6568542494924 + 7.2801098892805 + 6 + 7 + 5.6568542494924 = 31.5938183883 units
