OpenStudy (anonymous):

i need help so i can do my work

OpenStudy (anonymous):

I found it :)

OpenStudy (anonymous):

Okay Nadia, do you know how to find the area of a triangle?

OpenStudy (anonymous):

not really, im in 6th grade

OpenStudy (anonymous):

Okay :) The formula for a triangle is base x height divided by two

OpenStudy (anonymous):

So find the area of all three triangles :)

OpenStudy (anonymous):

ok so would it be A,B,C,o?

OpenStudy (anonymous):

opps D sorry

OpenStudy (anonymous):

Alright this is very tricky so stick with me like glue. Find the first triangle. e do 14x7 and that equals what?

OpenStudy (anonymous):

98

OpenStudy (anonymous):

Excellent. Now divide it by two

OpenStudy (anonymous):

so it would be 49

OpenStudy (anonymous):

Good! You found the area of one triangle :) Now find the second

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

Do 7x7 and divide it by two

OpenStudy (anonymous):

Because that is the formula for a triangle of course :P

OpenStudy (anonymous):

24.5

OpenStudy (anonymous):

then do you add it

OpenStudy (anonymous):

Very good. Now the third triangle

OpenStudy (anonymous):

Wait, no adding yet

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

You have to find the area of ALL the triangles first

OpenStudy (anonymous):

what is the next triangle?

OpenStudy (anonymous):

The next triangle. 7x14 divide by two

OpenStudy (anonymous):

49

OpenStudy (anonymous):

Good :) And finally the last triangle

OpenStudy (anonymous):

there's another??

OpenStudy (anonymous):

Yes um.....there is four. Their split up...

OpenStudy (anonymous):

so you do 7x7 divided by two?

OpenStudy (anonymous):

Yes :)

OpenStudy (anonymous):

Then add those numbers up and you should get your answer :)

OpenStudy (anonymous):

which is 24.5

OpenStudy (anonymous):

Wait, what?

OpenStudy (anonymous):

then you d o24.5+24.5+49+49

OpenStudy (anonymous):

Oh yes sorry lol

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

What is your answer Nadia. A, B, C, or D

OpenStudy (anonymous):

so the answer is b. 147cm2

OpenStudy (anonymous):

You got it :)

OpenStudy (anonymous):

OpenStudy (anonymous):
