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

4 u |
Area of Rectangle T is the repeated identity.
Shaded area of Rectangle T is the same as the shaded area of Square U.
LCM of 4 and 5 = 20
Fraction of Square U that is shaded
=
