The figure, not drawn to scale, is made up of Rectangle G and Rectangle H overlapping each other. The area of Rectangle G is
12 the area of Rectangle H. Given that
12 of Rectangle G is shaded. What fraction of the total area of the figure is unshaded?
Rectangle G |
Rectangle H |
1x2 = 2 u |
2x2 = 4 u |
Shaded area |
Unshaded area |

1 u |
1 u |
3 u |
Rectangle G and Rectangle H share the same shaded area.
Rectangle G is the combined repeated identity. Make the area of Rectangle G the same. LCM of 1 and 2 is 2.
Total unshaded areas
= 1 u + 3 u
= 4 u
Total area of the figure
= 1 u + 1 u + 3 u
= 5 u
Fraction of the figure unshaded
=
