The figure, not drawn to scale, is made up of Rectangle L and Rectangle M overlapping each other. The area of Rectangle L is
35 the area of Rectangle M. Given that
13 of Rectangle L is shaded. What fraction of the total area of the figure is unshaded?
Rectangle L |
Rectangle M |
3x1 = 3 u |
5x1 = 5 u |
Shaded area |
Unshaded area |
Shaded area |
Unshaded area |
1x1 |
2x1 |
1x1 |
|
1 u |
2 u |
1 u |
4 u |
Rectangle L and Rectangle M share the same shaded area.
Rectangle L is the combined repeated identity. Make the area of Rectangle L the same. LCM of 3 and 3 is 3.
Total unshaded areas
= 2 u + 4 u
= 6 u
Total area of the figure
= 1 u + 2 u + 4 u
= 7 u
Fraction of the figure unshaded
=
