a) a' = 8 * 5 = 40
b' = 12 * 5 = 60
c' = 16 * 5 = 90
L = a' + b' + c' = 40 + 60 + 90 = 190 cm
b) a' = 1/8 * 5 = 5/8
b' = 1/8 * 12 = 3/2 = 12/8
c' = 1/8 * 16 = 2
L = 5/8 + 12/8 + 16/8 = 33/8 = 4 i 1/8
b' = 12 * 5 = 60
c' = 16 * 5 = 90
L = a' + b' + c' = 40 + 60 + 90 = 190 cm
b) a' = 1/8 * 5 = 5/8
b' = 1/8 * 12 = 3/2 = 12/8
c' = 1/8 * 16 = 2
L = 5/8 + 12/8 + 16/8 = 33/8 = 4 i 1/8
