Answer :
Answer:
5 boxes is needed or 10 kg of seeds so yes!!
Step-by-step explanation:
first of all we know that the area of 9by 5 (9x5) is 45 and 45=3 kg of seed, so divide 45 ( the area) by 3 (the amount of kg) and so 45 ÷ 3 is 15 so now you have a UNIT of 1kg for every 15 square Meters, and 140 needs a little more than 9.3 kg worth of seeds so she has enough :)
The other words are just meant to be confusing just think of ratios :P
1kg:15m
