a) (5,5m + 5,5m) + (2,5m + 2,5m) = 11m + 5m = 16m
5,5m*2 + 2,5m*2 = 11m + 5m =16m
b) (3,5m + 3,5m) + (2,45m + 2,45m) = 7m + 4,9m = 11,9m
3,5m*2 + 2,45m*2 = 7m + 4,9m = 11,9 m
c) (4,55m + 4,55m) + (2,55m + 2,55m) = 9,1m + 4,1m =13,2m
4,55m*2 + 2,55m*2 = 9,1m + 4,1m = 13,2m
d) (3,75m + 3,75m) + (2,25m + 2,25m) = 7,5m + 4,5m = 12m
3,75m*2 + 2,25m*2 = 7,5m + 4,5m = 12m
