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

K |
J |
H |
K + L |

Since H and J form
12 of the square, the sum of the areas of H and J is the same as the sum of the areas of K and L.
Sum of L and H
= 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 L and H to the whole square =
