Step-by-step explanation:

Perimeter of rectangle is [tex]2x^{2} +8x+16[/tex].

What is perimeter of rectangle?

The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.

Given

Length of a rectangle in terms of x = [tex]x^{2} +2x+5[/tex]

Width of a rectangle in terms of x = [tex]2x+3[/tex]

Perimeter of rectangle = 2(length + width)

P = [tex]2(x^{2} +2x+5 + 2x+3)[/tex]

P = [tex]2(x^{2} +4x+8)[/tex]

P = [tex]2(x^{2} )+2(4x)+2(8)[/tex]

P = [tex]2x^{2} +8x+16[/tex]

Hence, Perimeter of rectangle is [tex]2x^{2} +8x+16[/tex].
