Answer 1

Answer: Perimeter and Area of the final poster will be 168 cm and 1728 cm² respectively.

Step-by-step explanation:

Since we have given that

Each student is to design a school poster.

Dimensions of rectangle are :

$12\ cm\ by\ 16\ cm$

It is then dilated by a scale factor of 3.

So, Perimeter of the final poster becomes

$3\times 2\times (L+B)\\\\=6(12+16)\\\\=6\times 28\\\\=168\ cm$

Similarly, Area of the final poster becomes

$3^2\times L\times B\\\\=9\times 12\times 16\\\\=1728\ cm^2$

Hence, Perimeter and Area of the final poster will be 168 cm and 1728 cm² respectively.
