1. The problem statement, all variables and given/known data In triangle ABC, ∠C=90∘. Let D, E, F be points on sides BC, AC, AB, respectively, so that quadrilateral CDFE is a rectangle. If [BDF]=7 and [AEF]=28, then find [ABC]. 2. Relevant equations Area of a rectangle, and triangle. Also can cut up the rectangle into some triangles 3. The attempt at a solution I'm not sure what [ABC] is. Is it asking for the perimeter or the area? I'm assuming area so I know the 1/2bh=28 for one and 7 for the other. I have to figure out some relation between those and the rectangle to get the sides of the rectangle in order to find the total area.
