Answer:
- shorter part: 12 ft
- longer part: 13 ft
Step-by-step explanation:
Let s represent the length of the shorter part (in feet). Then the longer part has length (s+1), and the total length of the two parts is ...
s + (s+1) = 25
2s = 24 . . . . . . . subtract 1, simplify
s = 12 . . . . . . . . . divide by 2; the length of the shorter part
s+1 = 13 . . . . . . . the length of the longer part
The shorter part is 12 feet long; the longer part is 13 feet long.

<em>Comment on this problem type</em>
You will note that the smaller number is half the difference of the total length (25) and the difference in lengths (1). This is the generic solution to a "sum and difference" problem. The smaller number is half the difference of the given numbers, and the larger number is half their sum: (25+1)/2 = 13.
