1. Oblicz skalę podobieństwa P2 do P1.
a) P1= 4cm i 7 cm P2= 4m i 7m
b) P1= 0,3m i 0,9m P2= 3km i 9km
a)P1=4·7=28cm² P2=400cm·700cm=280 000cm²
k²=P2/P1=280000/28=10000 to skala k=√10000=100
b)P1=0,3m·0,9m=0,27m² p2=3000m·9000m=27000000
k²=P2/P1=27000000/0,27=100000000 to k=√100000000=10000
a)
P1
4m = 400cm
7m = 700cm
P1 4 * 7 =28cm2
P2= 400 * 700 = 280000cm2
k= P2/ P1
k= 28oooocm2 / 28cm2
k= 10000
b)
0,3m = 0,003km
0,9m = 0,009km
P1= 0,003 * 0,009 = 0,000027km2
P2= 3 * 9 = 27km2
k= P2/P1
k= 27km2 / 0,000027km2
k= 1000000
