What is the perimeter of a triangle with sides measuring 6 feet 4 inches, 8 feet 3 inches, and 10 feet 6 inches?

• A. 24 feet 1 inch
• B. 25 feet 1 inch
• C. 26 feet 4 inches
• D. 27 feet 3 inches

Answer: (B)

To determine the perimeter of a triangle, you simply add the lengths of all three sides together. In this case, the sides are given in feet and inches, so it's important to ensure that the addition correctly accounts for both units.

First, convert the side lengths into inches for easier addition:

• 6 feet 4 inches = (6 x 12) + 4 = 72 + 4 = 76 inches

• 8 feet 3 inches = (8 x 12) + 3 = 96 + 3 = 99 inches

• 10 feet 6 inches = (10 x 12) + 6 = 120 + 6 = 126 inches

Next, add these values together:

76 inches + 99 inches + 126 inches = 301 inches

Now, convert the total inches back to feet and inches. There are 12 inches in a foot, so:

• 301 inches ÷ 12 = 25 feet with a remainder of 1 inch

Therefore, the perimeter of the triangle is 25 feet 1 inch, which is why this answer is correct.

This calculation demonstrates how to handle both feet and inches, ensuring an accurate perimeter determination by combining the
