Step-by-step explanation:

Equal sides = (3x-1)units and (2x-2)units

Third side= 2x units

Therefore,

3x-1 = 2x-2

3x-2x=-2+1

x=-1

first side = 2(-1)-2 = -4units

second side= 3(-1)-1 = -4 units

third side = 2(-1) = -2 units

Perimeter of triangle = side1+side2+side3

Therefore,

(-4)+(-4)+(-2)= 10units
