Perimeter = 3*25 = 75 cm

3 times 14cm = a perimeter of 42cm

3*3 = 9 cm

7 cm x 3 sides = 7 x 3 = 21 cm perimeter.

The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
