Welp. I sure hope you like the Pythagorean theorem... Top line: One point is (-2,-2) while the other is (3,-3) Thus the distance in between is sqrt((3-(-2))^2+(-3-(-2))^2)=sqrt(5^2+(-1)^2)=sqrt(26) Most right line: One point is (4,-6) while the other is (3,-3) Thus the distance in between is sqrt((3-4)^2+(-3-(-6))^2)=sqrt((-1)^2+3^2)=sqrt(10) Most bottom line: One point is (1,-6) while the other is (4,-6) Thus the distance in between is sqrt(4-1)^2+(-6-(-6))^2)=sqrt(3^2+0^2)=sqrt(9)=3 Most bottom left line: One point is (1,-6) while the other is (-2,-4) Thus the distance in between is sqrt((1-(-2))^2+(-6-(-4))^2)=sqrt(3^2+(-2)^2)=sqrt(13) Lastly the most left line: One point is (-2,-2) while the other is (-2,-4) Thus the distance in between is sqrt((-2-(-2))^2+(-2-(-4))^2)=sqrt(0^2+(2)^2)=sqrt(4)=2 Thus to find the perimeter, we add up all the sides to get sqrt(26)+sqrt(10)+3+sqrt(13)+2=16.8668 or B
