PROBLEM: A canvas tent is to be sewn to the
dimensions as shown. The tent consists of two side panels, each 10 feet by 10 feet; two end panels that are triangles, each 8 feet high and 12 feet at the base; and a floor that is 12 feet by 10 feet.

About how many square feet of canvas are used to make the tent (sides, ends, and floor)?

You need to figure out the area of each of the panels, and add them up. The side and floor panels are rectangles, with the area given by A = l * w.  The end panels are triangles, with the area given by A = 1/2 b * h.  Plug and chug! :-)

That makes no sense to me, and I have to pass this

Those are all of the pieces, labeled with their dimensions.  I gave you the formulas for finding their areas.  

Rectangle (which includes squares): A = l * w
Triangle: A = 1/2 * b * h

Now does it make sense?
