b1 = 4 cm
k = 2
k = a2/a1 = b2/b1
a2 = 2a1 = 2 * 1,2dm = 2,4 dm
b2 = 2b1 = 2 * 2cm = 4 cm
LUB
k = 2
k =a1/a2 = b1/b2
a2 = a1/2 = 1,2dm/2 = 0,6 dm
b2 = b1/2 = 4cm/2 = 2 cm
b=4cm
I przypadek
a'/a=b'/b=k
k=2
a'=a*k=1,2dm*2=2,4dm=24cm
b'=b*k=4cm*2=8cm
II przypadek
a/a'=b/b'=k
a'=a/k=1,2dm:2=0,6dm=6cm
b'=b/k=4cm:2=2cm
