4. a) 26

Step-by-step explanation:

2(PT) = AE              2(CP) = AN                 2(CT) = EN

2(13) = AE               2(29) = AN                  2(CT) = 43

  26 = AE                  58  = AN                      CT  = 21.5

Perimeter = AE + AN + EN

                = 26 + 58 + 43

                = 127
