Sean has 12.6 meters of garden netting. He needs 15.85 meters to enclose his garden. How many more meters of netting does Sean need to buy? Estimate to tell if your solution is reasonable. Show your work.
Answers
Answer: 3.25 meters
Explanation:
From the question, we are informed that Sean has 12.6 meters of garden netting and that he needs 15.85 meters to enclose his garden.
The meters of netting that Sean need more would be gotten by subtracting 12.6m from 15.85m. This will be:
= 15.85 - 12.6
= 3.25 meters
He needs 3.25 meters more
