The figure, not drawn to scale, consists of 1 Rectangle D and 1 Square E whose areas are in the ratio of 4 : 1. Given that
110 of Rectangle D is shaded, what fraction of Square E is shaded?
Area of Rectangle D |
Area of Square E |
4x5 = 20 u |
1x5 = 5 u |
Unshaded area |
Shaded area |

2 u |
Area of Rectangle D is the repeated identity.
Shaded area of Rectangle D is the same as the shaded area of Square E.
LCM of 4 and 10 = 20
