The following table shows the length and width of a rectangle: Length Width Rectangle A 4x 5 3x − 2 Which expression is the result of the perimeter of rectangle A and demonstrates the closure property? 14x 6; the answer is a polynomial 14x 6; the answer may or may not be a polynomial 2x 6; the answer is a polynomial 2x 6; the answer may or may not be a polynomial.

Respuesta :

The perimeter of the rectangle, for the dimensions shown in table is (14x+6) and the perimeter is polynomial.

What is perimeter of rectangle?

The measure of the boundary of a rectangle is called its perimeter. Perimeter of a rectangle is the sum of all the sides.

The perimeter of a rectangle is twice the sum of its length and width. It can be given as,

[tex]P=2(w+l)[/tex]

Here (w) is the width of the rectangle and (l) is the length of the rectangle.

The width of the rectangle is,

[tex]w=3x-2[/tex]

The length of the rectangle is,

[tex]l=4x+5[/tex]

As the perimeter of rectangle is twice the sum of its length and width. Thus the perimeter of the given rectangle is,

[tex]P=2[(3x-2)+(4x+5)]\\P=2[3x-2+4x+5]\\P=2[7x+3]\\P=14x+6[/tex]

As the perimeter of the given rectangle in the above equation is in the polynomial form. Thus, the perimeter of the rectangle is (14x+6) and the perimeter is polynomial.
