Solution

## The correct option is B Length=63 units Length=43 unitsArea of square wooden piece=249 sq. units The denominator here is 9, and the numerator is 24, respectively. So, the number 2, 3, 4, 6, 8 and 12 has to be the numerator of the side length of the square because 2 × 12 = 24 3 × 8 = 24 4 × 6 = 24 By seeing the options, only 'a' has numerator as 6 and option 'b' has the numerator as 4. Now, denominators can be 3 only, because: 3 × 3 = 9 So, Only option 'a' matches both the denominator and the numerator. 63×43=249 So, the correct option is option 'a'.
