Hi teman teman!! bisa minta tolong bantu aku kerja nomor 9? Beserta caranya yaaaa... makasih :)

diketahui :
[tex]l \: total = 3 \frac{3}{4} \: h = \frac{15}{4} \: h \\ p1 = 1 \frac{1}{2} \: h = \frac{3}{2} \: h \\ p2 = 1 \frac{5}{6} \: h = \frac{11}{6} \: h[/tex]
ditanyakan : petak 3 (p3)?
jawab :
[tex]p3 = l \: total - p1 - p2 \\ p3 = \frac{15}{4} - \frac{3}{2} - \frac{11}{6} \\ p3 = \frac{45}{12} - \frac{18}{12} - \frac{22}{12} = \frac{5}{12} \: hektar[/tex]
