A.
[tex]P = 9 \cdot 9 = \boxed{81 \ j^2}[/tex]
B.
[tex]420 : 4 = \boxed{105}[/tex]
C.
[tex]P = 5 \cdot 102 = \boxed{510 \ j^2}[/tex]
D.
[tex]Ob = 24 + 24 + 32 + 32 = \boxed{112}[/tex]
E.
[tex]P = 30 \cdot 4 = \boxed{120 \ j^2}[/tex]
F:
[tex]Ob = 44 :4 = 11\\P = 11 \cdot 11 = \boxed{121 \ j^2}[/tex]
