Odpowiedź:
a)
Pole = 4 x 1 cm = 4 (cm2
)
Pole = 3 x 1 = 3 (cm2)
Pole calego = 3 + 4 = 7 (cm2)
b)
Pole = 1 x 1 = 1 (m2)
Pole = 1 x 1 = 1 (m2)
Pole = 3 x 1 = 3 (m2)
Pole = 3 x 1 m = 3 (m2)
Pole = 2 x 1 = 2 (m2)
Pole calego = 1 + 1 + 3 + 3 + 2 = 10 (m2)
c)
Pole = 5 x 5 = 25 (m2)
Pole = 3 x 3 = 9 (m2)
Pole calego = 25 - 9 = 16 (m2)
d)
Pole = 5 x 1 = 5 (m2)
Pole = 5 x 1 = 5 (m2)
Pole = 5 x 1 = 5 (m2)
Pole = 1 x 1 =1 (m2)
Pole = 1 x 1 = 1 (m2)
Pole calego = 5 + 5 + 5 + 1 + 1 = 17 (m2)
Szczegółowe wyjaśnienie:
mam nadzieje ze pomoglem sory ze tak dlugo licze na naj ;)
