Answer 2

Answer:

i) 76 km  (ii)  82 cm  (iii)  88 m    (iv)  84 m

Step-by-step explanation:

Note :  ( )  is missing

(i)  perimeter = (7 +12) + 4 +12 + (15) + 7 + 19

                    = 76 km

(ii)  perimeter = 23 + 18 + 16 +10 +7 + (8)

                      = 82 cm

(iii)  perimeter = 16+ 20 + 24 + (7) + 8 + 13

                      = 88 m

(iv)  perimeter = 12 + (25) + 7 + 5 + (5) + 30

                       =  84 m
