The figure, not drawn to scale, is made up of Square C and Rectangles D and E. The area of Square C is
89 of the total area of Rectangles D and E.
14 of Square C is shaded.
14 of Rectangle D is shaded.
15 of Rectangle E is shaded. What fraction of the figure is shaded?

Comparing C and the
total of D and E |
8x1 =
8 u |
9x1 =
9 u |
| Total |
4x2 =
8 u |
4x1 =
4 u |
5x1 =
5 u |
| Shaded |
1x2 =
2 u |
1x1 =
1 u |
1x1 =
1 u |
| Unshaded |
3x2 =
6 u |
3x1 =
3 u |
4x1 =
4 u |
The area of C is repeated. Make the area of C the same. LCM of 8 and 4 is 8.
When C is 8 u, the total areas of D and E is 9 u.
Then adjust the values of D and E so that the total areas of D and E is equal to 9 u.
