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

Comparing R and the
total of S and T |
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 R is repeated. Make the area of R the same. LCM of 8 and 4 is 8.
When R is 8 u, the total areas of S and T is 9 u.
Then adjust the values of S and T so that the total areas of S and T is equal to 9 u.
