Perimeter of triangle is adding all three sides.

For example a triangle with sides 3, 5, and 7 would have a perimeter of 15

Now we use your values.

632 = (x) + (3x) + (3x + 2)

632 = 7X + 2

630 = 7x

90 = X

So side 1 is 90

Side 2 is 3 (90) or 270

Side 3 is 3 (90) + 2 or 272

Add all those up and you get (you guessed it) 632
