What is the area of the parallelogram Round to the nearest tenth of a meter?

Answer 1

Can't do it Monique. The area depends on the size and angles of the sides; you've given us none of these. But I can give you an equation to plug in those numbers if you have them to come up with the area.

generally area = A = area of the box + area of the triangles = L*l sin(alpha) + l^2 sin(alpha)cos(alpha); where the length of the parallel sides is L + l cos(alpha) and l is the diagonal length of each slanted side (of a triangle). Alpha is the angle of the slanted sides relative to a parallel side.

NOTE: the "box" is the rectangle made up of the two parallel sides minus the lengths of the two triangles. Also note the two triangles fit together to form a smaller box; so we multiply its sides for the area the triangles contribute.
