Answer:
The side lengths are 9, 9 and 7.
Explanation:
The sum of the 2 equal sides plus the shorter side is 25 ft.
Representing these unknowns:
2 sides are of length s, and the third (shortest) side is then s - 2.
Thus, s + s + (s - 2) = 25, or 3s = 27. Thus, s = 9 and s-2 = 7
The side lengths are 9, 9 and 7.
