The square is divided into 4 parts, Q, R, S and T. Q and R form
12 of the square. The area of T is double of the area of S, while the ratio of the area of R to the area of Q is 1 : 7. What fraction of the square is the sum of the area of T and Q? Leave your answer in the simplest form.
T |
S |
R |
Q |
S + T |

Since Q and R form
12 of the square, the sum of the areas of Q and R is the same as the sum of the areas of S and T.
Sum of T and Q
= 16 u + 3 u
= 19 u
Area of the square
= 16 u + 8 u + 21 u + 3 u
= 48 u
Fraction of the sum of the areas of T and Q to the whole square =
