You have to add up all the lengths for all the sides. Or you could multiply one side by four.

you just take the length of it's midsegment and multiply it by its height to find area. to find it's perimeter, just add the measures of it's sides

for perimeter add up the lengths of the six sides and for area divide the hexagon into six equilateral triangle, find the area of one, and multiply the product by six

The perimeter is the sum of the sides of a polygon. So, to find the perimeter of a pentagon, you need only to add up the 5 side lengths. In the event the pentagon is regular (all equal sides and angles) then you can multiply the measure of the side by 5 to get the perimeter.

Yes, for the perimeter of a polygon, you add up all the sides.
