Answer:
The perimeter of any cross section that is parallel to side AEHD will be [tex]12\ in[/tex]
Step-by-step explanation:
we know that
The side AEHD is a square
The perimeter of a square is equal to
[tex]P=4b[/tex]
where
b is the length side of the square
we have
[tex]b=3\ in[/tex]
substitute
[tex]P=4(3)=12\ in[/tex] -----> perimeter of side AEHD
therefore
The perimeter of any cross section that is parallel to side AEHD will be [tex]12\ in[/tex]
