# Help me help him Geometry/Algebra Which one of you moms is good at Algebra?

**I'm trying to fing the pereimter of an irregular polygon with missing sides. It seems easy but then I get confused. WE could wait until our tutoing session bu the problem is pissing me off. LOL**

**So???? Who can help? It's one were several sides are missing and I know there must be an easy formula.**

*Some people recognize the light but they can't handle the glare. *

**Not me! I'm struggling over here with my own homework. I'm trying my hardest to solve these rational expressions. Did I mention this already a developmental math class? LOL!**

Thanks! I'm going to send a picture of the text book problem.

Quoting MsNeene:

How many sides does the polygon have. And how many sides did they already give you the number for and what are those numbers? Then I can write you up a quick formula and solve it

31-18 = 13

25-13=12 (the horizontal section just above the 25m)

20+20+12+31+25+18 = 126 m

The perimetre is 126 metres

How were you calculating to get the answer? Just curious if it was a shorter method than what I had.

Quoting Dana267:

So I feel like there us a simple formula ----I know I'm doing too many steps to get the answer. There has to be an easier way.
