The figure, not drawn to scale, is made up of Square J and Rectangles K and L. The area of Square J is
89 of the total area of Rectangles K and L.
14 of Square J is shaded.
14 of Rectangle K is shaded.
15 of Rectangle L is shaded. What fraction of the figure is unshaded?

Comparing J and the
total of K and L |
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 J is repeated. Make the area of J the same. LCM of 8 and 4 is 8.
When J is 8 u, the total areas of K and L is 9 u.
Then adjust the values of K and L so that the total areas of K and L is equal to 9 u.
Unshaded areasTotal area =
6 + 3 + 4 8 + 3 + 4 =
