Triangle RJM has an area of 13 and a perimeter of 21. If the triangle is dilated by a scale factor of 3 centered at the origin, what are the area and perimeter of its image, triangle R'J'M'? * Your answer

Respuesta :

[tex]\begin{gathered} \Delta RJM\colon \\ A=13 \\ P=21 \end{gathered}[/tex]

After the dilatation:

[tex]\begin{gathered} \Delta R^{\prime}J^{\prime}M^{\prime}\colon \\ A=3\times13=39 \\ P=3\times21=63 \end{gathered}[/tex]
