Explanation:

Step1: Calculate perimeter of pink triangle

Perimeter = sum of all sides = \(14 + 14 + 10\) = \(38\) yd.

Step2: Calculate perimeter of green triangle

Perimeter = sum of all sides = \(15 + 9 + 12\) = \(36\) yd.

Step3: Compare perimeters

\(38 > 36\), so pink triangle (first figure) has greater perimeter.

Answer:

The pink triangle (with sides 14 yd, 14 yd, 10 yd) has a greater perimeter.
