Szczegółowe wyjaśnienie:
zadanie 35
((23+11) x 12) :2 = 204 m
zadanie 37
4x4= 16
(4x4) :2 = 8. 8 x4=32
16+32= 48cm
Zadanie 35
110dm=11m
P= 1/2 x (a+b) x h
1/2 x (23+11) x 12
1/2 x 34 x 12
(skracam 1/2 z 12)
34 x 6 = 204m2
204m2 = 2.04 arów
Zadanie 37
Pc = Pp + Pb
Pp = 4cm x 4cm = 16 cm2
Pb = 4(1/2 x a x h)
4(1/2 x 4 x 4)
(skracam 1/2 z 4)
4(2 x 4)
4 x 8
32cm2
Pc = 16cm2 + 32cm2
Pc = 48cm2
