First you must find the length of the 3 lines and then add them
from A to B  ( 1 ( 2 ) ) 2 + ( 3 1 ) 2 = 3 2 + 2 2 = 9 + 4 = 13 3.6 from B to C  ( 4 1 ) 2 + ( 3 3 ) 2 = 32 + ( 6 ) 2 = 9 + 36 = 45 6.7 from C to A  ( 4 ( 2 ) ) 2 + ( 3 1 ) 2 = 6 2 + ( 4 ) 2 = 36 + 16 = 52 7.21 the perimeter  3.6 + 6.7 + 7.21 17.51
