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.
Change in area = (change in sides)2
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.)
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.
The perimeter, being a linear measure, also changes by a factor of 3.
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).
The absolute value of the perimeter doesn't change, only the unit value which increases by a factor of 3.
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
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.
A perimeter that will not change.
No. Current is directly proportional to voltage, and it is inversely proportional to resistance. Resistance may depend on temperature, but the change is relatively small.
hi! no the current squared is directly proportional to the change in temp, Joules Law
