Change in area = (change in sides)2
If it is a 2-dimensional figure then it is proportional.
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.
No but if it is enlarged its dimensions are changed
when reducing or enlarging the dimensions you obviously have to change the dimensions. but do not change the ratio of the vaules. also do not cahnge the unit of the values.
Equal means they're the same thing. However, proportional means that they have the same rate of change. For example, a rectangle that is 4x8 is proportional to one that is 12x24 because the rate of change is 3 for both measurements.
If the new linear dimensions are k times the old dimensions, then the new area is k2 times the old area.
If it is a 2-dimensional figure then it is proportional.
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
The speed at which a reactant will change to a product is proportional to its concentration. This relationship is described by the rate law of the reaction. Changes in other factors, such as temperature and the presence of catalysts, can also affect the reaction rate.

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.)
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.
A hot barrel can affect the accuracy of a firearm by causing the metal to expand, which can change the dimensions of the barrel and affect the trajectory of the bullet. This can lead to decreased accuracy and consistency in shot placement.

Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.

Mass doesn't change. Mass the is substance of an object, moving it around won't affect how much mass it has, only adding or subtracting from the object would affect the quantity of mass. The weight would change because gravity is inversely proportional to distance but not the mass.
