Answer

Yes

Work Step by Step

The perimeter of a square varies directly with the side length of the square because as you increase the perimeter, a side length of the square increases as well, Also you could find the constant of change as well. Since there are 4 sides congruent sides in a square, the change in the perimeter relays 1/4 of the change to each side. So, 1/4 or 0.25 would be our constant. If you want to write an equation with that, we can substitute this for k in the standard form of a direct variation (y=kx): Equation: y=0.25x
