Tomorrow, students will be re-tested on finding area and perimeter of rectangles and triangles. Yesterday and today we did an activity with manipulatives to help students understand how to find the area of a triangle. You can imagine the triangle as half of a rectangle, for which the area is LxW. The area of a triangle, then, is 1/2(LxW). You can go to the following link for an interactive demonstration.
