OpenStudy (anonymous):
p=s+s+s+s
OpenStudy (goldphenoix):
Like I said, you do (2L) + (2W)

the area
OpenStudy (goldphenoix):
You do Length * Width / 2
OpenStudy (goldphenoix):
Why do you divide by 2? Well it's because a triangle is half a rectangle.

No. The length is vertical, so it looks like ________
So what do you think the length is?

The height is 4. Well yes, in this case, the longest side is the length.
OpenStudy (goldphenoix):
So plug it in. What would the area be?
OpenStudy (anonymous):
ok so the length x height /2?
