Sue has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.

What does the polygon look like?

- anonymous

I'm not sure where to start? and how to do it. ):

- anonymous

So you have no ideas at all at this point?

- anonymous

No im sorry... im just confused.

- anonymous

ok, ok... and what math is this?

- anonymous

Yes..

- anonymous

I mean like is this Algebra or geometry or what?

- anonymous

Like which class

- anonymous

geometry i think

- anonymous

its 6th grade math

- anonymous

ohhhhhhhhh I see

- anonymous

yeah

- anonymous

And this picture is the exact picture?

- anonymous

yes but i made it on here where it says draw

- anonymous

One of your sides says 25ft, but another side that is shorter says 35ft. Im just wondering ifthat was a typo?

- anonymous

No its exact

- mathstudent55

Usually with a compound polygon like that, you try to divide it into two or more smaller simpler polygons whose areas you know how to calculate. For example, divide it into rectangles, squares, trapezoids, triangles.

- anonymous

I know that part but i just dont know how i should do it i dont wanna do it wrong. @mathstudent55

- anonymous

Also one of your sides is cut off so i cant see the measure

- anonymous

Its all the way to the right

- anonymous

|dw:1434041096387:dw|

- anonymous

its is 43ft

- anonymous

|dw:1434041125332:dw|

- anonymous

the middle rectangle would be 8*35

- anonymous

uh huh

- anonymous

|dw:1434041171151:dw|

- anonymous

what is 43-35?

- anonymous

8

- anonymous

good job!

- anonymous

thanks

- anonymous

|dw:1434041240323:dw|

- anonymous

what is 8*8/2?

- anonymous

32?

- anonymous

yes good job!

- anonymous

(:

- anonymous

|dw:1434041311588:dw|

- anonymous

you understand why we did that, right?

- anonymous

yes to find that area

- anonymous

yes becaues the area of a triangle is 1/2*Base*Hieght

- anonymous

yep

- anonymous

Do you know what 35*8 is?

- anonymous

280 i think

- anonymous

yes

- anonymous

and you know what 33-8 is?

- anonymous

25

- anonymous

|dw:1434041496831:dw|

- anonymous

Do you know how to do the rest?

- anonymous

add 280 + 25+ 32 ?

- anonymous

|dw:1434041595334:dw|
We still have to find that triangle

- anonymous

25?

- anonymous

No, its side is 25. We have to find its other side and multiply the two and divide by two

- anonymous

oh

- anonymous

um

- anonymous

How dpo we find it?

- anonymous

-do

- anonymous

|dw:1434041926192:dw|
You're sure that side "X" is actually 25?

- anonymous

yes

- anonymous

hmmmmmm

- anonymous

|dw:1434042045583:dw|
If the other side is 43, then how can that one be 25?

- anonymous

i didnt create the question its on my worksheet

- anonymous

But are you sure that you copied the question right??

- anonymous

yes i have it with me

- anonymous

lets see if @mathstudent55 can help us

- anonymous

alright

- anonymous

Bump the question up to the top real quick

- anonymous

thank you though for attempting to help me when the question was a bit confusing.

- anonymous

ok

- anonymous

its loading hold on

- anonymous

ok

- anonymous

there

- anonymous

one sec im going to be right back

- anonymous

ok

- anonymous

help please?

- anonymous

and you're absolutely %100 sure that the problem is copied exactly??

- anonymous

yes i promise

- anonymous

is the problem multiple choice?

- anonymous

no written

- anonymous

well... i dunno... If i were you i would assume the other side to be 25. Then do 1/2*25*25. and then add 280 and 32 to it

- anonymous

i cant assume i need to know because i need to get it correct

- anonymous

then call the other side "X" and do 1/2*25*X. and then add on 280 and 32

- anonymous

i just need help understanding and doing it...

- anonymous

im just going to close question and start over

- anonymous

hold on, brb

- anonymous

ok

- anonymous

Can you please help me im begging. Was he doing it right?

- anonymous

I need to know the answer but i need know how to do it

- Here_to_Help15

area of triangle: 1/2 * b * h = 1/2 * 25 * 27 = 337.5 ft^2
area of trapezoid: 1/2 * (a + b)h = 1/2 * (43 + 35)(8) = 312 ft^2
total area: 337.5 ft^2 + 312 ft^2 = 649.5 ft^2

- anonymous

so the answer is 649.5?

- anonymous
