Erin has scanned a 4 × 5-inch postcard, and she wants to reduce it to make a graphic for her web site. she will use a scale factor of 1 in. = 2 cm. . what will be the dimensions of the graphic?

Just multiply both dimensions by 2 to make it into centimeters.

Therefore,

4*2 x 5*2 (in inches) will be:

8cm x 10cm (in centimeters)

We conclude that the dimensions of her postcard into a graphic on her web page will be 8x10 in centimeter units. 

I hope my answer has come to your help. Thank you for posting your question here in .

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
