Answer:
The painter would need an additional 5.25 liters of paint for the rest of the fencing.
Explanation:
The painter used 5 liters and 250 milliliters of paint for painting one side of the square-shaped park's fencing. To find out how much more paint he would need for the rest of the fencing, we need to determine the total amount of paint required for all four sides.
Since a square has four equal sides, we can multiply the amount of paint used for one side by 4 to find the total amount needed for all four sides.
To convert 250 milliliters to liters, we divide it by 1000, since there are 1000 milliliters in one liter. So, 250 milliliters is equal to 0.25 liters.
The total amount of paint needed for all four sides is:
5 liters + 0.25 liters = 5.25 liters
