It's too much trouble to look for it, Jessica, but I think we have done this problem for you in the last couple of days. Perhaps it was another student.
area triangle = area rectangle.
rectangle = 8" x 12" = 98 in<sup>2</sup>.
area triangle = 96 in<sup>2</sup>.

area triangle = 1/2*base*height.
96 in<sup>2</sup> = 1/2*32*h
solve for h. I gret 6"

Area of the rectangle is length * width. Aread of the triangle is 1/2 base * height.

The length and width are given. Multiply them to find the area. Take that area to the triangle formula. Area = 1/2 base * height. The base is given. The only unknown is the height. That is solved by the equation. If you do the calculations you will get a number that is in the answer list.
