Answer:
J. 126
Explanation:
To answer this it is basically like direct proportion so
You make the mixed numeral into an improper fraction (multiply the denominator with the big number and then add the numerator):
To find the hallway of finished building in metres you divide the blueprint's measurement with the representative measurement (sorry if it is not clear)
÷
Then you times 14 with 9m, which gives:
9 × 14 = 126m
So the answer is J
