A) √1600m²=40m
40m*4=160m
b)4a=400m²
√400m²=20m
20m*4=80m
c) 1,21 ha=121a=12100m²
√12100m²=110m
110m*4=440m

A) P = 1600m^2
1600 = a^2
a = 40m
Ob = 4 * 40 = 160m
b) P= 4a = 400m^2
400 = a^2
a = 20m
Ob = 4 * 20 = 80m
c) P = 1,21ha = 12100m^2
12100 = a^2
a = 110m
Ob = 4 * 110 = 440m

A) P=a^2
1600=a^2 / pierw
a=40m
L= 4a
L=4*40
L=160m. <--- tyle siatki potrzeba

b) 4a (1a=100m^2)
400m^2=P
400=a^2/pierw
a=20m.
L=4*a
L=4*20
L=80m <--- tyle siatki potrzeba

c)1.21ha (1ha=10000m^2)
12100m^2=P
12100=a^2 / pierw
a=110m.
L=110*4
L=440m <--- tyle potrzeba siatki
