if the length of a rectangle is 2x+1 and the width is x, what is the perimeter of the rectangle when x=6 centimeters? show the steps you used to determine the answer

The perimeter of a rectangle is given by

P =2(l+w)

P =2( 2x+1  + x)

Combine like terms

P = 2(3x+1)

Distribute

P = 6x+2

Let x=6

P = 6*6+2

   = 36+2

   = 38 centimeters
