Perimeter color(maroon)(p = 4 * (x - 2)

Explanation:

Perimeter of a rectangle p = 2 * (l + w)

Given l = x+2, w = -6

p = 2 * (x + 2 + x - 6)

Perimeter p = 4 * (x - 2)

4x-8

Explanation:

Perimeter of a rectangle is given by the equation:

P=2(l+w)

where:

  • l is the length of the rectangle

  • w is the width of the rectangle

So, we get:

P=2(x+2+x-6)

=2(2x-4)

=4x-8
