Zadanie 1
a) P - pole L - obwód
3dm = 30cm
2m = 200cm
[tex]P = 30cm * 200cm = 6000cm^2\\\\L = 30cm * 2 + 200cm * 2 = 60cm + 400cm = 460cm[/tex]
b)
[tex]P = 1,5dm * 1,5dm = 2,25dm^2[/tex]
[tex]L = 1,5dm * 4 = 6dm^2[/tex]
c)
a = 6cm
b = 6cm + 2cm = 8cm
[tex]P = 6cm * 8cm = 48cm^2\\\\L= 6cm * 2 + 8cm * 2 = 28cm[/tex]
d)
a = 6cm
b = 6cm * 2 = 12cm
[tex]P = 6cm * 12cm = 72cm^2\\\\L = 6cm * 2 + 12cm * 2 = 36cm[/tex]
