Cut the figure apart. Find separate areas and add. Hold on while I cut. You can look up the formula (if you don't know) for the area of a trapezoid and the area of a right triangle. Okay?

OpenStudy (anonymous):

its just really confusing how its set up?

Directrix (directrix):

Take a look at the diagram now.

OpenStudy (anonymous):

is the answer 48.96?

Directrix (directrix):

Now is the time for you to find the area of the trapezoid with bases of lengths 18 and 11.75 and height 6.12. What is the formula? @Foreverisabell

Directrix (directrix):

I don't yet know the answer. I am trying to help you learn how to find the answer without guessing. lol

OpenStudy (anonymous):

Okay I got it thanks one more please!

OpenStudy (anonymous):

Directrix (directrix):

I have to finish the first problem.

OpenStudy (anonymous):

I finished it. I got the answer.

OpenStudy (anonymous):

its 91.035.

Directrix (directrix):

> is the answer 48.96? NO

OpenStudy (anonymous):

I know. that. Can you just help me on the other one? thank you.

Directrix (directrix):

What did you get for the area of that trapezoid in the first problem you posted in this thread?

Directrix (directrix):

>its 91.035 NO

OpenStudy (anonymous):

it is 91.035 The area is base 1 + base 2 time h divided by 2

@Directrix

Directrix (directrix):

Oh, I thought you were talking about the entire figure. For the trap, I got 1/2*6.12*(11.75 + 18). Does that equal what you got for the trapezoid?

Directrix (directrix):

>it is 91.035 Correct for the trapezoid

OpenStudy (anonymous):

Im not sure it just says find the area of the trapezoid?

Directrix (directrix):

What did you get for the right triangle? (on first problem)

Directrix (directrix):

I have not looked at the second problem. We have not yet resolved the first problem. Or, I haven't.

OpenStudy (anonymous):

Yes we have. So can you help me on the next problem please

Directrix (directrix):

What did you get for the triangle area in the first problem? If you work with me, I'll work with you on that second problem. Deal?

OpenStudy (anonymous):

Can you help me on the second one first though I really need help

Directrix (directrix):

I'm working on the second problem while you find the area of a right triangle with legs 13.42 and 12. After you get the area of that triangle, I have a question about that figure in the second question.

Directrix (directrix):

I know the answer to the second question - just waiting for that area of the right triangle to complete problem 1.

OpenStudy (anonymous):

Your confusing me. Can you tell me the answer for the second one & I will help you with the first one here in a second.

OpenStudy (anonymous):

@Directrix

Directrix (directrix):

The area of that right triangle - post it on this thread so we can complete problem 1. THEN, we will talk about the second problem.
