Maya created several possible ways to rearrange her hamster's cage to give the hamster more room to run around. Her drawings were made with a scale factor of 1:2, but she wants to change the scale factor to 1:6 so she can compare them more easily.

The diagram shows the lengths of the sides of her first scale drawing and the scale factors relating both drawings to the actual cage.

Identify the scale factor that relates the two scale drawings to each other. Then, find the length and width of the smaller scale drawing.

Scale Factor of 1:2 is
12 In top and bottom
6 left and right

Scale factor 1:6 unknown

The new scale factor is 1/2 ÷ 1/6 = 3

The widow the new rectangle is *blank 1* *blank 2* *blank 3* = *blank 4*
The width of the new rectangle is *blank 5* inches

Options for blank 2

To find the scale factor that relates the two scale drawings to each other, we can compare the original scale factor of \(1:2\) to the new scale factor of \(1:6\).

The relation can be expressed as: \[ \text{Scale factor between drawings} = \frac{1/2}{1/6} = \frac{1}{2} \times \frac{6}{1} = 3 \] This means the first drawing is \(3\) times larger than the second drawing.

Now, we can find the lengths for the smaller drawing (1:6 scale).

The original dimensions for the \(1:2\) scale drawing are:

  • Length: \(12\) inches
  • Width: \(6\) inches

To convert these dimensions to the \(1:6\) scale, we divide each dimension by \(3\) (the scale factor we just calculated).

For the length of the smaller scale drawing: \[ \text{Length} = \frac{12 \text{ inches}}{3} = 4 \text{ inches} \]

For the width of the smaller scale drawing: \[ \text{Width} = \frac{6 \text{ inches}}{3} = 2 \text{ inches} \]

Thus, the filled in statements in your structure would look like this:

The widow (window) of the new rectangle is \(12 \text{ inches} ; \text{(length)} , \text{blank 1} , 6 \text{ inches} ; \text{(width)} ; \text{blank 2} = 4 \text{ inches} \) (new length \(blank 4\)).

The width of the new rectangle is \(2 \text{ inches} \) (blank 5).

Therefore:

  • Blank 1 = ÷ (to denote the relationship).
  • Blank 2 = = (to denote the equality).
  • Blank 4 = 4 inches (the calculated new length).
  • Blank 5 = 2 inches (the calculated new width).

So, to summarize:

  • The scale factor relating the two drawings is \(3\).
  • The length of the new rectangle is \(4\) inches.
  • The width of the new rectangle is \(2\) inches.
