Question

Tracy dilates the square below. The perimeter of the dilated square is 84 millimeters.

Square has 6mm

Answer 1

Let's denote the side length of the dilated square as x.

Since Tracy dilated the square by a factor of x/6, the perimeter of the dilated square can be calculated as 4 * x = 84.

Therefore, x = 84 / 4 = 21 mm.

So, the side length of the dilated square is 21 mm.
