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

15 u |
Since T and U form
12 of the square, the sum of the areas of T and U is the same as the sum of the areas of V and W.
Sum of W and T
= 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 W and T to the whole square =
