A. L = s x s = 5,5 x 5,5 = 30,25 cm Kll = 4 x s = 4 x 5,5 = 22 cm b. L = s x s = 16 x 16 = 256 cm Kll = 4 x s = 4 x 16 = 64 cm c. L = s x s = 60 x 60 = 3600 m Kll = 4 x s = 4 x 60 = 240 m d. L = s x s = 1008 x 1008 = 1016064 dm Kll = 4 x s = 4 x 1008 = 4032 dm
= 5,5 x 5,5
= 30,25 cm
Kll = 4 x s
= 4 x 5,5
= 22 cm
b. L = s x s
= 16 x 16
= 256 cm
Kll = 4 x s
= 4 x 16
= 64 cm
c. L = s x s
= 60 x 60
= 3600 m
Kll = 4 x s
= 4 x 60
= 240 m
d. L = s x s
= 1008 x 1008
= 1016064 dm
Kll = 4 x s
= 4 x 1008
= 4032 dm
