What is the perimeter of a rectangle 7 in by 2 in enlarged by the scale factor of 1.5?
A rectangle 10.5 x 3 will have a perimeter of 27 in.
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.
The area of a rectangle is 36 sq inches. Which of these is not a possible perimeter 40 in 36 in 26 in 18 in?
18" is not a possible perimeter measurement. Assume the dimensions of the rectangle are so close to those of a square that the difference can be disregarded. This is the condition when the perimeter is at its minimum. When the rectangle measures approximately 6" x 6", its area = 36 sq ins, its perimeter = 24" For the area to remain constant then as the length increases by a factor n the width must decrease by that same factor. Area = 6n x 6/n : perimeter = 12n + 12/n :so when n = 1, Perimeter = 12 + 12 = 24 As n increases, say n = 2, Perimeter = 24 + 6 = 30 : And the perimeter continues to increase as the rectangle becomes narrower. Eventually, it will become so narrow that for diagram purposes it will appear as a straight line.
What does it mean if the length and width of a rectangle is doubled?
If the length and width of a rectangle is doubled, it means that both dimensions have increased by a factor of 2. As a result, the area of the rectangle will increase by a factor of 4, because the area is calculated by multiplying the length and width together. Additionally, the perimeter of the rectangle will also increase by a factor of 2, since it is calculated by adding the lengths of all four sides.
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.

If a rectangular dimensions ge multiplied by 4 what does the perimeter get multiplied by?
The perimeter correspondingly increases by a factor of 4.

When the sides of a polygon are tripled in length the perimeter increases by a factor of and the area increases by a factor of?
Perimeter is proportional to the linear dimensions, so it increases by 3x .Area is proportional to (linear dimensions)2, so it increases by 9x .
How do you find the ratio of the perimeter of two similar rectangles?
The ratio of the perimeters is equal to the scale factor. If rectangle #1 has sides L and W, then the perimeter is 2*L1 + 2*W1 = 2*(L1 + W1).If rectangle # 2 is similar to #1 and sides are scaled by a factor S, so that L2 = S*L1 and W2 = S*W1, the perimeter of rectangle #2 is 2*(L2 + W2)= 2*(S*L1 + S*W1) = S*2*(L1 + W1) = S*(perimeter of rectangle #1).

Suppose the side lengths of a rectangle are halved. what would happen to the perimeterr?
If the side lengths of a rectangle are halved, the perimeter of the rectangle would also be halved. This is because the perimeter of a rectangle is calculated by adding the lengths of all four sides. If each side length is halved, then the total length around the rectangle would also be halved.
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.
What are all the possible dimensions of the rectangle with an area of 54?
To find the possible dimensions of a rectangle with an area of 54, we can consider pairs of factors of 54. The factor pairs are (1, 54), (2, 27), (3, 18), (6, 9). Therefore, the possible dimensions of the rectangle are: 1 by 54, 2 by 27, 3 by 18, and 6 by 9.
How do you use the dimensions of a rectangle to find factor pairs?
I think you are thinking of using the rectangles like you use Punnet squares. One side is multiplied times the other side and the product is put in the inside squares. This is handy when trying to factor expressions that are polynomials.
