Answer:
The lateral area of the prism is [tex]84\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The lateral area of the regular prism is equal to
[tex]LA=Ph[/tex]
where
P is the perimeter of the base of the prism
h is the height of the prism
Find the perimeter of the base
[tex]P=6(3.5)=21\ cm[/tex] ----> is a regular hexagon (6 equal sides)
we have
[tex]h=4\ cm[/tex]
substitute
[tex]LA=(21)(4)=84\ cm^{2}[/tex]
