Question

The printed matter on a 10-cm by 12-cm page of a book must cover 48 cm2. If all margins are to be the same width, how wide should they be?
a. 4 cm

b. 3 cm

c. 2 cm

d. 1 cm

Answer 1

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.
