The square is divided into 4 parts, L, M, N and P. L and M form
12 of the square. The area of P is double of the area of N, while the ratio of the area of M to the area of L is 1 : 6. What fraction of the square is the sum of the area of M and N? Leave your answer in the simplest form.
P |
N |
M |
L |
N + P |

Since L and M form
12 of the square, the sum of the areas of L and M is the same as the sum of the areas of N and P.
Sum of M and N
= 18 u + 7 u
= 25 u
Area of the square
= 14 u + 7 u + 18 u + 3 u
= 42 u
Fraction of the sum of the areas of M and N to the whole square =
