side 1 3 units
side 2 x+7
Side 3 2x-2
3+x+x+7+2x-2 = 32
4x+8=32
4x=32-8=24
x=6

~~~~~~~~~~~~~~~~~~~~~
The solution by @mananth is FATALLY WRONG due to his arithmetic errors.
See my correct solution below.
The sides are 3 units, (x+7) units and (2x-2) units.
The equation for the perimeter is
3 + (x+7) + (2x-2) = 32.
Simplify and find x
3 + x + 7 + 2x - 2 = 32,
x + 2x = 32 - 3 - 7 + 2,
3x = 24
x = 24/3 = 8 units. <<<===--- ANSWER
The sides of the triangle are 3 units, 8+7 = 15 units and 2*8-2 = 14 units.
CHECK. The perimeter is 3 + 15 + 14 = 32 units. ! correct !
Solved correctly.
