Szczegółowe wyjaśnienie:
Jednostki zamieniam w głowie
Poziom b
[tex]ah = 4 \times 0.9 = 3.6c {m}^{2} [/tex]
[tex]ah = 3 \times 21 = 63 {cm}^{2} [/tex]
[tex]ah = 50 \times 0.8 = 40c {m}^{2} [/tex]
[tex]ah = 11 \times 4 = 44 {mm}^{2} [/tex]
[tex]ah = 4.5 \times 20 = 90 {cm}^{2} [/tex]
[tex]ah = 6.3 \times 0.5 = 3.15 {cm}^{2} [/tex]
[tex]ah = 1.2 \times 4 = 4.8 {dm}^{2} [/tex]
[tex]ah = 13 \times 8 = 104 {dm}^{2} [/tex]
Poziom c
[tex]a) \: \frac{ef}{2} \\ \frac{16 \times 12}{2} = 96 {cm}^{2} [/tex]
[tex]b) \: ah \\ 4 \times 5 = 20 {cm}^{2} [/tex]
[tex]c) \: ah \\ 3 \times 3 = 9 {cm}^{2} [/tex]
