How does proportional change in the dimensions affect the perimeter of a figure?

If you are asking how the perimeter of an object changes if the whole object is proportionally changed: The perimeter changes by the same factor as the change in proportion of the whole object.
For example: given a square that is 2 units by 2 units, changed by a factor of four, the new size would be 8 units by 8 units. The original perimeter was 2+2+2+2=8. The new perimeter is 8+8+8+8=32. So, multiplying the original perimeter, 8, by the factor of proportional change, 4, we get 8x4=32.
For any object, multiply the original perimeter by the factor of proportional change to arrive at the new perimeter.

How does the proportional change in the dimensions affect the area of a polygon?
Change in area = (change in sides)2
When both dimensions of a figure are changed using the same scale factor is the change proportional or non proportional?
If it is a 2-dimensional figure then it is proportional.
How does the perimeter change when the dimensions are changed by a scale factor of 3?
The perimeter, being a linear measure, also changes by a factor of 3.
Does the perimeter of a rectangle change when you double the dimensions?
Yes. The perimeter is a measure of the combined length of all the sides. If you double the lengths of the sides then naturally this will also necessarilychange the perimeter (it will double the perimeter).
How does the perimeter of a figure change if the dimensions are changed from yards o feet?
The absolute value of the perimeter doesn't change, only the unit value which increases by a factor of 3.
How does the proportional change in the dimensions affect the area of a polygon?
Change in area = (change in sides)2
How does proportional change in the dimensions affect the area of a figure?
If the new linear dimensions are k times the old dimensions, then the new area is k2 times the old area.
How do the area and perimeter of the area of a figure change when it's dimensions change?
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)

How does the perimeter and area of a square change when its dimensions change?
A 3 x 3 square has perimeter 12 and area 9 A 6 x 6 square has perimeter 24 and area 36 Double the dimensions, double the perimeter, quadruple the area. Mathematically, a square with side x has a perimeter of 4x and an area of x2 Doubled, a square with side 2x has a perimeter of 8x and an area of 4x2
How does the perimeter of a figure change if the dimensions are changed from yards o feet?
The absolute value of the perimeter doesn't change, only the unit value which increases by a factor of 3.
How is the perimeter and the size change factor related?
If you change the scale factor of a geometric figure by a factor "x", that is, keeping the new figure similar to the old one, the perimeter (which is also a linear measurement) will change by the SAME factor "x".Note that any area will change by a factor of x squared.
What is strain in physics?
Strain is the change in dimensions per unit original dimensions. For example, if your stretch a 100 cm long wire by 5 cm, Strain = 5/100 = 0.05
What is a fixed perimeter?
A perimeter that will not change.
Why is it capacitance does not affect current in a Direct Current circuit?
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
