A dilated shape will either be enlarged or compressed.
<em>Allen did not make any mistake, and the scale factor is 3.</em>
The dimension of the smaller rectangle (figure Z) is:
3 units by 4 units
The corresponding dimension of the bigger rectangle (figure Z') is:
9 units by 12 units
The scale factor (k) is calculated by dividing the dimensions of Z' by Z.
So, we have:


or


Notice that both values of k are the same (i.e. 3)
This means that the scale factor is 3
Also figure Z and Z' share the same center of origin at point X
This means that the center of dilation from Z to Z' is X
Hence,
Allen made no mistake, and she is correct about the scale factor.

Answer/Step-by-step explanation:
Scale factor: 1/4
<em>AC = DF and 10 ÷ 2.5 = 4</em>
<em>10 x 1/4 = 2.5</em>
<em />
DE length: 5
<em>AB = DE </em>
<em>20 x 1/4 = 5</em>
<em />
BC length: 30
<em>EF = BC</em>
<em>(Because EF is the dilation) 7.5 x 4 = 30</em>
