The ratio of the areas of similar triangles is equal to the square of the ratio of their corresponding sides. Given the area ratio = 1:16, the side ratio = √1:√16 = 1:4. Perimeter of the original triangle = 15 + 20 + 25 = 60 cm. Perimeter of the smaller triangle = 60 ÷ 4 = 15 cm. Correct answer: a) 15 cm
