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 : 7. What fraction of the square is the sum of the area of K and L? Leave your answer in the simplest form.
| M |
L |
K |
J |
L + M |
K + J |
| 2x8 |
1x8 |

| 16 u |
8 u |
21 u |
3 u |

24 u |
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
= 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 K and L to the whole square =
