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 : 6. What fraction of the square is the sum of the area of L and H? Leave your answer in the simplest form.
| L |
K |
J |
H |
K + L |
J + H |
| 2x7 |
1x7 |

| 14 u |
7 u |
18 u |
3 u |

21 u |
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
= 14 u + 3 u
= 17 u
Area of the square
= 14 u + 7 u + 18 u + 3 u
= 42 u
Fraction of the sum of the areas of L and H to the whole square =
