What is the missing side length of an irregular pentagon with side lengths nineteen point nine centimeters, twenty-four point eight centimeters, thirty centimeters and forty-nine point two centimeters, if the perimeter is equal to the perimeter of a regular hexagon with side length twenty-six centimeters?

Question

e.mccormick · Answer

pentagon  means 5 sides, hexagon means 6.  Irregular means different length sides and angles.  Regular means same sides and angles.  So the regular hexagon can get you a perimeter and from that you find the missing side of the pentagon.  What part of this process is giving you trouble?

so it's 6.1?

I got a different value.
HexSide*6=sum of all five of pentagon.

Looks like the site is slowing, so I am going tojust put in the formula so you can see where I was going with this.  Another way of saying that is:
(26)(6)=19.9+24.8+30+49.2+x

Now solve for x.
