Answer :

Final answer:

You will need more wood to repair the fence and you will need an extra 2.1 meters of wood for the fence.

Explanation:

Since you have 7.9 meters of wood and you need 10 meters to repair the fence, you will need more wood to repair the fence. So, option 1: You will need more wood to repair the fence is correct.

Also, since you do not have enough wood to meet the requirement of 10 meters, option 2: You have enough wood to repair the fence is incorrect.

To calculate how much extra wood you need, you can subtract the 7.9 meters you already have from the 10 meters you need. So, 10 - 7.9 = 2.1 meters. Therefore, option 3: You will need an extra 2.1 meters of wood for the fence is correct.

Since you do not have enough wood, you will have none left after repairing the fence. Therefore, option 4: You will have 2.1 meters of wood left after repairing the fence is incorrect.
4 you will have 2.1 meters of wood left over
