1:121

For all polygons the area is proportional to the multiplication of base and hight. Which again i proportion to the side length. So ratio of their areas should be 1:11^2 i.e. 1:121

Let us consider an square of side 1 and another of side 11,
the ratio of two areas equals : 1*1 / 11*11 = 1/ 121
The ratio is 1 / 121
