The square is divided into 4 parts, N, P, Q and R. N and P form
12 of the square. The area of R is double of the area of Q, while the ratio of the area of P to the area of N is 1 : 7. What fraction of the square is the sum of the area of P and Q? Leave your answer in the simplest form.
| R |
Q |
P |
N |
Q + R |
P + N |
| 2x8 |

Since N and P form
12 of the square, the sum of the areas of N and P is the same as the sum of the areas of Q and R.
Sum of P and Q
= 21 u + 8 u
= 29 u
Area of the square
= 16 u + 8 u + 21 u + 3 u
= 48 u
Fraction of the sum of the areas of P and Q to the whole square =
