If the perimeter of the rectangle is 22 centimeters, what are its dimensions?Found 2 solutions by kelsdf, Alan3354:Answer by kelsdf(2)   (Show Source): You can put this solution on YOUR website!Let's make the width equal x. That would make the length 3x+3. If the perimeter is 22, the formula is length+length+width+width or 2length+2width. So we would plug in our variables giving us the equation: 2x+[2(3x+3)]=22. Multiply and you'd get 2x+6x+6=22. Subtract 4 from each side to get 2x+6x=16. Add like terms giving you: 8x=16 Divide both sides 8 to get x=2. Plug in 6 to get x=6 and 3x+3=21. So your length would be 21 and your width would be 6.

If the perimeter of the rectangle is 22 centimeters, what are its dimensions? ------------ L = 3W + 3 2L + 2W = 22 Sub for L into eqn 2 2(3w+3) + 2W = 22 3W+3 + W = 11 4W = 8 W = 2 cm ----------- L = 9 cm
