The square is divided into 4 parts, V, W, X and Y. V and W form
12 of the square. The area of Y is double of the area of X, while the ratio of the area of W to the area of V is 1 : 4. What fraction of the square is the sum of the area of Y and V? Leave your answer in the simplest form.
| Y |
X |
W |
V |
X + Y |
W + V |
| 2x5 |
1x5 |
|
|
3x5 |

4x3 |
1x3 |
|
5x3 |
| 10 u |
5 u |
12 u |
3 u |
15 u |
15 u |
Since V and W form
12 of the square, the sum of the areas of V and W is the same as the sum of the areas of X and Y.
Sum of Y and V
= 10 u + 3 u
= 13 u
Area of the square
= 10 u + 5 u + 12 u + 3 u
= 30 u
Fraction of the sum of the areas of Y and V to the whole square =
