Prostokąt 1:
[tex]a = 4cm\\b = 2cm\\\\Obw. = 2 \cdot 4cm + 2 \cdot 2cm = 8cm + 4cm = \boxed{\bold{12cm}}\\P = 4cm \cdot 2cm = \boxed{\bold{8cm^2}}[/tex]
Prostokąt 2:
[tex]a = 5cm\\b = 1cm\\\\Obw. = 2 \cdot 1cm + 2 \cdot 5cm = 2cm + 10cm = \boxed{\bold{12cm}}\\P = 1cm \cdot 5cm = \boxed{\bold{5cm^2}}[/tex]
