A quadrilateral (X1) is obtained by joining the mid-points of a second rectangle. Further, a rectangle is obtained by joining the mid points of quadrilateral (X1) obtained above. Again another quadrilateral (X2) is obtained by joining the mid points of the second rectangle. This process is repeated for an infinite number of times. Find the ratio of the sum of areas of all the rectangles to the sum of the areas of all the quadrilaterals (X1, X2...).
Please Explain the approach..
