I'd suggest you find the area of the polygon first, and then worry about the first question. What are the dimensions of the rectangle? What are the dims. of the triangle?

OpenStudy (anonymous):

find the distance of BC and BD

OpenStudy (mathmale):

Good suggestion. What would the purpose of that step be?

OpenStudy (mathmale):

Dan: Try to involve @fluffynose in the solution of this problem. Give her only enough help so that she can do one step of the solution at a time.

OpenStudy (anonymous):

what is the perimeter of a triangle @fluffynose

OpenStudy (anonymous):

@mathmale that is exactly what am doing :)

OpenStudy (anonymous):

are you with me @fluffynose

OpenStudy (fluffynose):

oh hold on idk how to find out perimeter

OpenStudy (anonymous):

but do you know the distance formula

OpenStudy (fluffynose):

nosiir

OpenStudy (anonymous):

the perimeter of a triangle is A+B+C

OpenStudy (anonymous):

In finding distance is \[\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\]

OpenStudy (fluffynose):

Okay whats the x1 x2 and y1 and y2?

OpenStudy (mathmale):

If I'm reading this problem statement correctly, we want the perimeter of the whole figure, not including the dividing line BD. So, for the triangle, we need ONLY the lengths of sides BC and CD (which lengths are the same). Then, move on to find the lengths of the sides of the rectangle AB, DE and AE.

OpenStudy (fluffynose):

Where do you get those from

OpenStudy (mathmale):

From the given illustration, of course. Take a look at it, please.

OpenStudy (anonymous):

mathmale is right

OpenStudy (mathmale):

Very sorry, but my statement "If I'm reading this correctly" is partially wrong. You are to find the perimeters of the rectangle and of the triangle separately, which is what Dan started out doing. So, finish this work, please. Then find the ratio of the perimeter of the rectangle to the perimeter of the triangle. Then, move on to finding the area of the whole figure.

OpenStudy (mathmale):

I need to leave this conversation, but have faith in Daniel's ability to help you (Fluffy) solve this problem yourself.

OpenStudy (fluffynose):

Hahaaa i got the naswer now thanks guys!

B=(2,6) C=(6,3) D=(2,0)
