OpenStudy (pleasehelp2346677):

I got 360 but that's incorrect

OpenStudy (prathamesh_m):

You need to find the area of the three rectangles and the two triangles.

OpenStudy (pleasehelp2346677):

Do I multiply each face by the height?

OpenStudy (prathamesh_m):

What did you consider as the height of the triangles?

OpenStudy (pleasehelp2346677):

That's where I run into a problem, I'm not sure how to find that

OpenStudy (prathamesh_m):

If you observe closely, it'll be 8 inches since the side of that rectangle will line up alongside the height of the triangle.

OpenStudy (prathamesh_m):

So area of the triangles will be: 0.5 x 15 x 8 Area of the rectangles will be: 17 x 9, 15 x 9 and 8 x 9.

OpenStudy (pleasehelp2346677):

0.5 x 15 x 8 = 80 17 x 9 = 153 15 x 9 = 135 8 x 9 = 72

OpenStudy (pleasehelp2346677):

so do I add all of them to get my answer? @Prathamesh_M

OpenStudy (prathamesh_m):

Yes and you add the triangle twice since there are two of them.

OpenStudy (pleasehelp2346677):

so 80 + 80 +153 +135 + 72?

OpenStudy (prathamesh_m):

Yes.

OpenStudy (pleasehelp2346677):

that gives me 520. So there's my answer?
