A(-6,2),B(-3,6),and C(5,0) ?
D=SQRT[(X2-X1)^2+(Y2-Y1)^2]
D=SQRT(-3+6)^2+(6-2)^2=SQRT(3^3+4^2)=SQRT(9+16)=SQRT25=5 ANS. A TO B.
D=SQRT(5+3)^2+(0-6)^2=SQRT(8^2-6^2)=SQRT(64+36)=SQRT100=10 ANS. B TO C.
D=SQRT(5+6)^2+(0-2)^2=SQRT(11^2-2^2)=SQRT(121+4)=SQRT125=11.18 ANS. C TO A.
5+10+11.18=26.18 ANS. FOR THE PERIMETER.
