Question

If the rectangle below were to be enlarged by a scale factor of 5, what would the new size be? 2 10 x 15 10 X 6 8 X 15 Od 2 X 3

Answer 1

To dilate a shape by a determined scale factor, you have to multiply each side of the said shape by the scale factor.

The figure is a rectangle with length l=3 and width w=2, to enlarge it using factor 5, you have to multiply both lengths by 5:

`\begin{gathered} l=3\cdot5 \\ l=15 \end{gathered}`
`\begin{gathered} w=2\cdot5 \\ w=10 \end{gathered}`

After dilating the rectangle by scale factor 5, the new size will be 10 x 15
