Question 1045171
The area of a rectangle is the product of its length and width. A rectangular poster has an area of 260 square inches. The width of the poster is greater than 10 inches and is a prime number. What is the width of the poster?
<pre>If the length is an INTEGER, then: {{{highlight_green(matrix(1,14, The, width, can, be, one, (1), and, only, one, (1), number, and, "that's", 13))}}}
If the length IS NOT an integer, the width can be any PRIME NUMBER between 17 and 257, inclusive. 
However, a poster that's {{{matrix(1,3, 257, by, 260/257))}}} would not make much sense, and neither would others that have disproportionate lengths and widths.
