Step-by-step explanation:

The length, in feet, of a rectangular rug is represented by the expression 5x^2 + 2x. . The width, in feet, is represented by the expression 3x^2.

The perimeter of the rectangle is

$P=2\text{ lengths}+2\text{ widths}.$

Thus, the perimeter is

$P=2(5x^2+2x)+2\cdot 3x^2=10x^2+4x+6x^2=16x^2+4x.$
