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.
What else can I help you with?
How does the proportional change in the dimensions affect the area of a polygon?
Change in area = (change in sides)2
Does changing the area affect the perimeter?
Yes, changing the area of a shape can affect its perimeter, but the relationship is not straightforward. For instance, increasing the area of a rectangle can be achieved by altering its length and width, which may increase or decrease the perimeter depending on how the dimensions are adjusted. However, for shapes with fixed proportions, such as circles, an increase in area will always result in an increase in perimeter (circumference). Ultimately, the effect of area change on perimeter depends on the specific shape and how its dimensions are modified.
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.
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 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.
How does the proportional change in the dimensions affect the area of a polygon?

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 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 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.
Why does the perimeter of a rectangle change?
The perimeter of a rectangle changes when the lengths of its sides alter. Since the perimeter is calculated by adding together the lengths of all four sides (P = 2(length + width)), any increase or decrease in the length or width will directly affect the total perimeter. For instance, if one side is lengthened or shortened, the overall perimeter increases or decreases accordingly. Thus, any modification to the dimensions of the rectangle will result in a change in its perimeter.
Is there a relationship between area and perimeter of a rectangle and Why?
Yes, there is a relationship between the area and perimeter of a rectangle, although they measure different aspects. The area is calculated by multiplying the length by the width, while the perimeter is the sum of all sides, given by the formula ( P = 2(l + w) ). As the dimensions of a rectangle change, both area and perimeter can increase or decrease, but they do not have a direct proportional relationship; for instance, a rectangle can have the same perimeter but different areas depending on its length and width.
Can you make the perimeter of your shape go up but the area go down using grid?
Yes, it is possible to increase the perimeter of a shape while decreasing its area using a grid. For example, if you take a rectangle and stretch it to make it longer and thinner, the perimeter will increase due to the added length of the sides, but the area can decrease if the width is reduced sufficiently. This demonstrates that perimeter and area are not directly proportional and can change independently based on the shape's dimensions.
Can the perimeter of a rectanlge be larger than the area?
Yes, the perimeter of a rectangle can be larger than its area. For example, consider a rectangle with dimensions 1 unit by 1 unit, which has a perimeter of 4 units and an area of 1 square unit. As the rectangle's dimensions change, especially when one dimension is much larger than the other, the perimeter can exceed the area even more significantly.
