Answer:

14 m

Step-by-step explanation:

Let the shorter side be x

Then the longer side is x + 1

<u>Perimeter is:</u>

P = 2( x + x + 1) = 2(2x + 1) = 4x + 2

The value of perimeter is at most 60 meters. P ≤ 60.

<u>Solve the inequality:</u>

4x + 2 ≤ 60
4x ≤ 58
x ≤ 58/4
x ≤ 14.5

Since x is the integer, its greatest value is 14 m
