Verify that dilations scale line segments by the dilation scale factor.

Separate length, perimeter, and area dilation factors

Problem

Determine each two-dimensional measure change under a dilation with \(k=2\).

Big Picture

What this problem is really about

Dilation factors depend on dimensionality. We’ll scale generic side lengths by k, factor that same multiplier from the perimeter sum, multiply the two independently scaled dimensions for area, and use the resulting powers of k to keep linear measures separate from square-unit measures.
