The figure, not drawn to scale, is made up of Rectangle N and Rectangle P overlapping each other. The area of Rectangle N is
15 the area of Rectangle P. Given that
15 of Rectangle N is shaded. What fraction of the total area of the figure is unshaded?
Rectangle N |
Rectangle P |
1x5 = 5 u |
5x5 = 25 u |
Shaded area |
Unshaded area |
Shaded area |
Unshaded area |
1x1 |
4x1 |

1 u |
4 u |
1 u |
24 u |
Rectangle N and Rectangle P share the same shaded area.
Rectangle N is the combined repeated identity. Make the area of Rectangle N the same. LCM of 1 and 5 is 5.
Total unshaded areas
= 4 u + 24 u
= 28 u
Total area of the figure
= 1 u + 4 u + 24 u
= 29 u
Fraction of the figure unshaded
=
