Question

A square has 9 inch sides . Every side of a pentagon is also 9 inches long are the perimeters the same

Answer 1

No because a pentagon has more sides than a square does.
to find perimeter you have to add up all the sides.
for the square it would be 9+9+9+9 which is 36

for the pentagon it would be 9+9+9+9+9 which is 42.
