Bok najpierw
[tex]16 \div 4 = 4cm[/tex]
Pole najpierw
[tex] {4}^{2} = 16 {cm}^{2} [/tex]
Bok potem
[tex]150\% \times 4cm = 1.5 \times 4 = 6cm[/tex]
Pole potem
[tex] {6}^{2} = {36cm}^{2} [/tex]
O ile procent się zwiększyło
[tex]16 {cm}^{2} - 100\% \\ 36 {cm}^{2} - x \\ \\ x = \frac{36 \times 100}{16} = \frac{3600}{16} = 225\%[/tex]
[tex]225\% - 100\% = 125\%[/tex]
O 125%
