Explanation:

Step1: Count the number of units of the fence

By counting the units of the fence on the coordinate grid, we find there are \(12\) units.

Step2: Convert units to feet

Since each unit represents \(5\) feet, the length in feet is \(12\times5 = 60\) feet.

Step3: Calculate the cost

The cost is \(\$10\) per foot. So the total cost is \(60\times10=\$600\).

Answer:

\(600\)
