Karlen took a piece of rope and made a square with it. Then he cut the rope into two pieces in the ratio 1:3 and made two different squares. Which is the increasing order of the areas of the three squares ?

Answer 1

so, say the rope has length 4
The perimeters of all three squares are in order, 1,3,4
So now you can get the sides, and then the areas, right?
