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

L |
K |
J |
L + M |
K + J |

Since J and K form
12 of the square, the sum of the areas of J and K is the same as the sum of the areas of L and M.
Sum of K and L
= 12 u + 5 u
= 17 u
Area of the square
= 10 u + 5 u + 12 u + 3 u
= 30 u
Fraction of the sum of the areas of K and L to the whole square =
