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.
