The perimeter will be tripled.
3 cm, 4 cm and 5 cm because they are a Pythagorean triple
L is side length so perimeter is 4L. If L is tripled the perimeter becomes 4 x 3L = 12L, so perimeter is also tripled.
Any one dimension increased by 3, or any two dimensions increased by the square root of 3 or all three dimensions increased by the cube root of 3.
The perimeter would triple and the area would be multiplied by nine (32). Circumference (perimeter) is (2 x pi x r), so would be (6 x pi x r) for triple the radius, and area is (pi x r2), so would be (pi x 32 x r2) for triple the radius.
The area increases to 9 times as much.

Any one dimension increased by 3, or any two dimensions increased by the square root of 3 or all three dimensions increased by the cube root of 3.
x^2=3x(x-2)
Because of it's dimensions
When you triple the dimensions of a flat (2-dimensional) shape,the area increases by (3)2 = 9 times.When you triple the dimensions of a solid (3-dimensional) shape,the volume increases by (3)3 = 27 times.
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
Triple Action happened in 1981.
