Rectangle A measures 9inches by 3 inches, rectangle B is a scaled copy of rectangle A . What are all the measurements pairs that could be the dimensions of rectangle B

Answer:

Dimensions of Rectangle B will be 9x inches by 3x inches where x is a scaling factor.

Step-by-step explanation:

Scaled Copy: It means that the rectangle A is related to rectangle B by some scaling (multiplying) factor x.

As we are given Dimensions of rectangle A =  9 inches by 3 inches

Then for any scaling factor x the dimensions of rectangle B will be:

Dimensions of Rectangle B = x * ( Dimensions of rectangle A)

Dimension of rectangle B = x * (9 inches by 3 inches)

Dimensions of rectangle B = 9x inches by 3x inches

For more understanding let we assume that rectangle B is scaled copy of rectangle A by scaling factor x=3; then we will have the dimensions of rectangle B as under:

For scaling factor (x) = 3;

Dimensions of Rectangle B = x * ( Dimensions of rectangle A)

Dimensions of rectangle B = 3 (9 inches by 3 inches)

Dimensions of rectangle B = 27 inches by 9 inches

On the other hand for scaling factor x=0.75, the dimensions of rectangle B will become as under;

Dimensions of Rectangle B = x * ( Dimensions of rectangle A)

Dimensions of rectangle B = 0.75 (9 inches by 3 inches)

Dimensions of rectangle B = 6.75 inches by 2.25 inches

The scale copy of a shape is the resulting shape when the original shape is dilated. Possible scaled rectangles of rectangle A are:

A. 6 inches by 2 inches

D. 3 inches by 1 inch

Given that:

[tex]Length = 9in[/tex]

[tex]Width = 3in[/tex]

Calculate the equivalent ratio (k)

[tex]k = \frac{Length}{Width}[/tex]

So, we have:

[tex]k = \frac{9in}{3in}[/tex]

[tex]k =3[/tex]

The equivalent ratio is 3.

So, a scaled copy of rectangle A must have an equivalent ratio of 3.

The scaled copies are:

A. 6 inches by 2 inches

Because:

[tex]k = \frac{6in}{2in}[/tex]

[tex]k=3[/tex]

D. 3 inches by 1 inch

Because:

[tex]k = \frac{3in}{1in}[/tex]

[tex]k=3[/tex]
