Answer:
6 m, 6 m, 5 m
Step-by-step explanation:
If x is the common length then the perimeter is the sum of side lengths:
x + x + (2x-7) = 17
4x = 24 . . . . . . . . . add 7
x = 6 . . . . . . . . . . divide by 4
2x -7 = 12 -7 = 5 . . . find the length of the 3rd side
The side lengths are 6 m, 6 m, and 5 m.
