. What is the perimeter of the figure?

OpenStudy (anonymous):

wat figure XD

OpenStudy (anonymous):

OpenStudy (goldphenoix):

You do (2L) + (2W) L= Length W= Width

OpenStudy (anonymous):

length x width?

OpenStudy (anonymous):

yes

OpenStudy (goldphenoix):

No. That's how you find the area.

OpenStudy (anonymous):

no

OpenStudy (anonymous):

add all the sides together lol

OpenStudy (anonymous):

p=s+s+s+s

OpenStudy (goldphenoix):

Like I said, you do (2L) + (2W) What's the length and the width of the rectangle?

OpenStudy (anonymous):

add all the side together lol

OpenStudy (anonymous):

9+9+3.5+3.5=?

OpenStudy (anonymous):

what about a triangle

OpenStudy (goldphenoix):

Finding the perimeter of a triangle?

OpenStudy (anonymous):

its a rectangle gabe lol

OpenStudy (anonymous):

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.

OpenStudy (goldphenoix):

Arg. My bad. Length * Height /2.

OpenStudy (goldphenoix):

So what's the length, and what's the height of that triangle?

OpenStudy (anonymous):

i dont know theres three sides but the height is 4

OpenStudy (goldphenoix):

Well, what do you think the length is?

OpenStudy (anonymous):

its the longest side right?

OpenStudy (goldphenoix):

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

OpenStudy (anonymous):

so its the dotted line in the middle?

OpenStudy (goldphenoix):

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?

OpenStudy (goldphenoix):

Yes What does that give you?

OpenStudy (anonymous):

22

OpenStudy (goldphenoix):

Yes. Good job.

OpenStudy (anonymous):

ok thanks :D
