The two squares,X and Y, are mathematically the same. The areas of X and Y are 19cm^2 and 304cm^2, respectively. The length of Y is 40 cm.Find the corresponding length of X please!!
The two areas you gave MUST be those of two rectangles scaled down by a ratio of: 19/304=1/16.
Therefore the given side will scale down as the ratio of the Sqrt of 1/16=1/4. Since the given side is 40, then the corresponding side of the rectangle will scale down as: 1/4 X 40=10. Therefore, the two sides of the larger rectangle are: 40 and 304/40=7.6. The two sides of the smaller rectangle are: 10 and 19/10=1.9. This hold true because, 1.9:10 is proportional to 7.6:40.
