Final answer:
Sally's strategy is incorrect as tripling the inches in 6 yards does not accurately represent the number of feet in 18 yards.
Explanation:
No, Sally's strategy does not work.
To find the number of feet in 18 yards, we know 1 yard is equal to 3 feet. If we triple the number of inches in 6 yards to find feet, it would be incorrect as the conversion factor inches to feet is not the same as yards to feet. So, her strategy is flawed.
Therefore, Sally's method of tripling the inches in 6 yards to find the number of feet in 18 yards is incorrect and does not work.
