[writes Area=ab] To find perimeter, we’ve been adding a and b and then doubling that sum. [writes Perimeter=(a+b)×2] Then we want the area and perimeter to be equal, so… (27) Lee: Oh, I see. We need to find rectangles with sides lengths a and b that make the area ab equal to the perimeter, which is… [pauses to write ab=2(a+b)] …twice the
