Answer:

Perimeter is 126cm and area is 972 $cm^2$

Step-by-step explanation:

Scale factor means you multiply the dimensions by the factor. In this case 4.5

The width 6cm becomes 27cm. The length 8cm becomes 36cm.

Perimeter = 2*L + 2*W, L is length and W is width.

$P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm$

Area = L*W

$A=27cm*36cm\\A=972cm^2$
