What is the area of the figure? http://static.k12.com/calms_media/media/1564500_1565000/1564709/1/a72cc27a06b3ed896381f19d35c4bec9213eb923/MS_IMB-1401012-1100606.jpg Medal if helped

OpenStudy (oblivion20):

can anyone help?

OpenStudy (anonymous):

do you know the formula? did you get a formula to understand how to work through it?

OpenStudy (oblivion20):

it doesn't give me a formula it just said i have to work out the problem

OpenStudy (oblivion20):

and find the area

OpenStudy (anonymous):

does it give you an answer selection? or is it fill in the blank

OpenStudy (oblivion20):

fill in the blank for the area

OpenStudy (anonymous):

Figure out the area of the parallelogram and then the area of the trapezoid. Do you know the formula for the areas?

OpenStudy (oblivion20):

for trapezoid it base times base times hight

OpenStudy (anonymous):

base 1 times base 2 times height, right, so figure out the formula for a parallelogram now

OpenStudy (anonymous):

Actually for a trapezoid it's \[A=\frac{ a+b }{ 2 }h\] and for a parallelogram it's A=bh

OpenStudy (oblivion20):

ok sorry

OpenStudy (anonymous):

my guess is 528, but i am not a math genius.. I did the formulas, then added them together at the end

OpenStudy (oblivion20):

then don't we divide by two??

OpenStudy (anonymous):

what did yo use for the height of the trapezoid? And yes you do divide by two

OpenStudy (anonymous):

for the height of the trapezoid i used 10... but im horrible

OpenStudy (oblivion20):

me and you both gummybear1021 I'm horrible at math

OpenStudy (anonymous):

Actually the height of the entire figure is 18, and the height of the parallelogram is 10. So 18-10 would be the height of the trapezoid.

OpenStudy (oblivion20):

so 8 is the hight

OpenStudy (anonymous):

Yes

OpenStudy (oblivion20):

k do we know the area yet?

OpenStudy (anonymous):

What does your formula look like for each of the shapes with the numbers put in?

OpenStudy (oblivion20):

what???.....

OpenStudy (anonymous):

Okay, does your formula for the trapezoid look like this?\[A=(\frac{ 8+24 }{ 2 })8\]

OpenStudy (oblivion20):

yeah

OpenStudy (anonymous):

okay, then what is the area of the trapezoid?

OpenStudy (oblivion20):

128

OpenStudy (oblivion20):

right? should be?

OpenStudy (anonymous):

yeah. And does your formula for the parallelogram look like this?\[A=(10)(24)\]

OpenStudy (oblivion20):

yeah

OpenStudy (anonymous):

okay, then what is the area of the parallelogram?

OpenStudy (oblivion20):

hold on

OpenStudy (oblivion20):

240?

OpenStudy (anonymous):

yes, then to get the total area you add the area of both figures together

OpenStudy (oblivion20):

368

OpenStudy (anonymous):

Yep, good job!

OpenStudy (oblivion20):

thank you i'm going to fan

OpenStudy (anonymous):

thanks!

OpenStudy (oblivion20):

you are oh so vary welcome
