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

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#

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#
