You can put this solution on YOUR website! A rectangle has a length (x-6)m and width (2x+3) calculate the perimeter
===============
P = 2W + 2L
P = 2{x-6)m + 2(2x+3)
P = 2mx - 12m + 4x + 6
I think you meant the "m" to be for "meters" (or "metres" if you are from UK).
Think of the word "perimeter" as "peRIMeter". See the word "RIM" inside? lol
Think of the perimeter as the RIM.
PERIMETER = DISTANCE ALL THE WAY AROUND THE RIM
PERIMETER = TOP SIDE + LEFT SIDE + BOTTOM SIDE + RIGHT SIDE
PERIMETER = (2x+3) + (x-6) + (2x+3) + (x-6)
= 2x + 3 + x - 6 + 2x + 3 + x - 6
= 2x + x + 2x + x + 3 - 6 + 3 - 6
= 6x - 6 meters
