A garden has four sides. Three sides measure 5.5 meters each, and one side measures 8.2 meters. Which of the following is the perimeter of the garden?

Rationale

The perimeter of the garden is 24.7 meters.

To find the perimeter of the garden, we sum the lengths of all four sides. The three sides measuring 5.5 meters contribute a total of 16.5 meters, and when we add the fourth side measuring 8.2 meters, the total perimeter becomes 24.7 meters.

A (16.5 meters) YOUR ANSWER

This choice only accounts for the three sides measuring 5.5 meters each, resulting in a total of 16.5 meters. It neglects the additional side measuring 8.2 meters, which is essential for calculating the full perimeter of the garden.

B (24.7 meters) CORRECT

This is the correct answer as it accurately represents the total perimeter calculated by adding all the sides together: 5.5 + 5.5 + 5.5 + 8.2 = 24.7 meters.

C (13.7 meters) YOUR ANSWER

This option does not correctly reflect the measurements of the garden sides. It underestimates the total perimeter significantly, suggesting a miscalculation or misunderstanding of the side lengths provided.

D (27.4 meters) YOUR ANSWER

This choice incorrectly suggests that the perimeter exceeds the actual sum of the side lengths. It appears to result from a possible mathematical error, such as incorrectly calculating one or more of the side lengths, leading to an inflated total.

Conclusion

The perimeter of a shape is determined by the sum of all its sides. For the garden in this question, the accurate calculation yields a perimeter of 24.7 meters, confirming that option B is correct. The other choices either result from miscalculations or fail to incorporate all the side measurements, highlighting the importance of careful addition in perimeter computations.
