I really need help on this! Please anyone ?

OpenStudy (mathmusician):

What is the question

OpenStudy (mtwizzle420):

OpenStudy (mtwizzle420):

I have this, that's all I can figure out though

OpenStudy (mtwizzle420):

@KendrickLamar2014

@Nnesha

OpenStudy (joannablackwelder):

Yep, that looks good so far. Do you know the formula for area of a trapezoid?

OpenStudy (joannablackwelder):

Ah, you have it written at the top of the page. Can you find the areas of each of the trapezoids using the area formula?

OpenStudy (mtwizzle420):

I need help with that honestly

OpenStudy (joannablackwelder):

Let's look at the top trapezoid. What is the height?

OpenStudy (mtwizzle420):

165

OpenStudy (joannablackwelder):

Great! And what are the lengths of the two parallel sides?

OpenStudy (mtwizzle420):

187.5 and 397.5

OpenStudy (joannablackwelder):

Great! Those are your b1 and b2. :-) Can you try plugging those numbers into the formula?

OpenStudy (mtwizzle420):

Yeah hold on one sec :)

OpenStudy (joannablackwelder):

Sure. :-)

OpenStudy (mtwizzle420):

A=82.5(187.5+397.5) A=15,468.75+32,793.75 A=48,262.5 A=112.5(397.5+225) A=44,718.75+25,312.5 A=70,031.25

OpenStudy (joannablackwelder):

Great! :-) Any thoughts from here?

OpenStudy (mtwizzle420):

I was thinking adding the two sums

OpenStudy (joannablackwelder):

Sounds good. :-)

OpenStudy (mtwizzle420):

118,293.75

OpenStudy (joannablackwelder):

Great! Any thoughts from here?

OpenStudy (mtwizzle420):

No now im lost

OpenStudy (joannablackwelder):

Ok, we are trying to find the cost of the land per square foot.

OpenStudy (joannablackwelder):

We have the cost of the land and the total square footage.

OpenStudy (joannablackwelder):

So, we can do the cost divided by the square footage to get the cost per square foot. :-)

OpenStudy (mtwizzle420):

3.83092936 so yes he could buy it because its less than 4$ correct? :)

OpenStudy (mtwizzle420):

How would I check this?

OpenStudy (joannablackwelder):

Yep, that's great! :-)

OpenStudy (joannablackwelder):

Hm, how to check it? Let me think.

OpenStudy (joannablackwelder):

I'm not really sure of a good way to check it, but what you did looks great! :-)

OpenStudy (mtwizzle420):

Thank you !!!!

OpenStudy (joannablackwelder):

You're welcome. :-)
