Odpowiedź:
a)
[tex]p = 2 \times \frac{8 \times 6}{2} + 6 \times 6 + 8 \times 6 + 10 \times 6 = 48 + 36 + 48 + 60 = 192[/tex]
b)
[tex]p = 2 \times 5 \times 5 + 4 \times5 \times 7 = 50 + 140 = 190 [/tex]
c)najpierw liczę "skośny bok"
4²+3²=x²
16+9=x²
x²=25
x=5
[tex]p = 2 \times \frac{(8 + 5) \times 4}{2} + 4 \times 10 + 2 \times 10 \times 5 = 52 + 40 + 100 = 192[/tex]
192+8×10=192+80=272
