What is the difference between the walkway perimeter and the pool perimeter given as 118 feet and 64 feet respectively?

• A. 44 feet
• B. 64 feet
• C. 118 feet
• D. 54 feet

Answer: (D)

The main concept here is subtracting to find how much bigger one quantity is than another. To compare the two perimeters, subtract the smaller from the larger: 118 feet minus 64 feet equals 54 feet. So the difference is 54 feet, meaning the walkway perimeter is 54 feet longer than the pool perimeter. The other numbers would just restate one of the perimeters or come from a miscalculation, but they don’t show how much larger the walkway is than the pool.
