Enlargement transformation and scale factor
An original display panel is changed to the image described below
The original quadrilateral has vertices W, X, Y, Z, in the order listed. Matching vertices in the image use the same labels with a prime mark
Original: \(WX=2\ \mathrm{cm}\); \(XY=2\ \mathrm{cm}\); \(YZ=2\ \mathrm{cm}\); \(ZW=3\ \mathrm{cm}\)
Image: \(W'X'=26\ \mathrm{cm}\); \(X'Y'=26\ \mathrm{cm}\); \(Y'Z'=26\ \mathrm{cm}\); \(Z'W'=39\ \mathrm{cm}\)
Use side WX and its matching image side to find the scale factor
Both figures above use the same drawing scale
Original close-up: drawn larger so you can see the corners. Use the pair above to compare sizes
