Answer:
The area in the enlarged version is (2.25 * 3.6) square inches
Step-by-step explanation:
Here, we want to get the area of the book in the enlarged version
From what we have
initial version is;
4 * 6
enlarged is 12 * 18
It means that; the dimensions were tripled from the initial to the enlarged
So a book cover of initial:
0.75 by 1.2
Its enlarged form will be;
(0.75 * 3) by (1.2 * 3)
= 2.25 * 3.6
