[tex]l \: = \: p \times l \\ 28\frac{1}{2} = p \times 4 \frac{3}{4} \\ p = 28 \frac{1}{2} \div 4 \frac{3}{4} \\ p = \frac{57}{2} \times \frac{4}{19} \\ p = \frac{114}{19} \: m \\ \\ kell \: = 2 \times (p + l) \\ = 2 \times ( \frac{114}{19} + \frac{19}{4} ) \\ = 2 \times( \frac{456}{76} + \frac{361}{76} ) \\ = 2 \times \frac{817}{76} \\ = \frac{1634}{76} \\ = 21 \frac{1}{2} \: m[/tex]
