I THINK it's A. But am not completely sure.
The perimeter is the sum of the length of the line segments.
Length of RS = sqrt((-2 - (-1))^2 + (7 - 3)^2) = sqrt((-1)^2 + 4^2) =sqrt(1 + 16) = sqrt(17) = 4.12 units
Length of ST = sqrt((2 - (-2))^2 + (5 - 7)^2) = sqrt(4^2 + (-2)^2) = sqrt(16 + 4) = sqrt(20) = 4.47 units
Length of TU = 3 units
Length of UR = 2 units
Perimeter = 4.12 + 4.47 + 3 + 2 = 13.6 units.
