The figure, not drawn to scale, consists of 1 Rectangle R and 1 Square S whose areas are in the ratio of 3 : 1. Given that
19 of Rectangle R is shaded, what fraction of Square S is shaded?
Area of Rectangle R |
Area of Square S |
3x3 = 9 u |
1x3 = 3 u |
Unshaded area |
Shaded area |
Unshaded area |

1 u |
Area of Rectangle R is the repeated identity.
Shaded area of Rectangle R is the same as the shaded area of Square S.
LCM of 3 and 9 = 9
