Answer 3

Calculating the Length of the Painted Fence

To calculate the length of the fence that has already been painted, we can use the given information that the total length of the fence is 12 meters and a part of it, 40 decimeters, still needs to be painted.

Given: - Total length of the fence = 12 m - Length remaining to be painted = 40 dm

Conversion of Length Units

First, we need to convert the length remaining to be painted from decimeters to meters.

Conversion: - 40 decimeters = 4 meters

Calculation

Now, we can calculate the length of the fence that has already been painted.

Calculation: - Total length of the fence = 12 meters - Length remaining to be painted = 4 meters - Length of the fence already painted = Total length - Length remaining to be painted - Length of the fence already painted = 12 meters - 4 meters - Length of the fence already painted = 8 meters

Final Answer

The length of the fence that has already been painted is 8 meters.
