Answer: The margins will be 2 cm
Step-by-step explanation: The factors of 48 that are likely to work are 6 by 8. While not exactly proportional to 10 by 12, 6 and 8 are both 4 less than the page size.
10-6 = 4
12-8 = 4
To have an even margin on all sides, divide the difference by 2
4/2 = 2
So a 2 cm margin will satisfy the requirements.
