Given the length and width, the expression for the perimeter of the rectangle is 10x - 16.

What is the expression for the perimeter of the rectangle?

The perimeter of rectangle is expressed as;

P = 2( l + w )

Where l is length and w is width.

Given the data in the question;

  • Length l =  3x+ 1
  • Width w = 2x - 9

Plug the given values in the equation above

Perimeter = 2( l + w )

Perimeter = 2( (3x+ 1) + ( 2x - 9) )

We can go on and simplify.

Perimeter = 2( (3x+ 1) + ( 2x - 9) )

Perimeter = (6x+ 2) + (4x - 18)

Perimeter = 6x+ 2 + 4x - 18

Perimeter = 10x - 16

Given the length and width, the expression for the perimeter of the rectangle is 10x - 16.
