Answers
Answer:
Quick answer, no it is not sufficient. The fertilisers only cover 1000 sq ft when the required is 1400 sq ft. You need 2 more bags of fertilisers.
Step-by-step explanation:
The area of the full field is 70 x 20ft = 1400 sqft.
If one bag of fertiliser covers 200 sq ft, and there are five, to get the total amount of area that the fertilisers cover, you need to do 200 x 5 = 1000.
This means the fertiliser only covers 1000 sq ft, and you still need 400 sq ft covered.
One bag = 200 sq ft. To get to 400, you just need to do 400 divided by 200 which is 2 - which means 2 more bags of fertilisers.
