Quote:
When the sides of two polygons are in proportion of x:y then the perimeters will be in proportion of x:y and the areas will be in the proportion of x^2:y^2
Here the perimeters' ratio \(= 5:9\)
Hence the area will be in proportion of \(5^2:9^2 = 25:81\)
Check for the options that are in the same proportion of \(25:81\)
Answer \(C D\)
