Answer:

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

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

5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.

Then 5x + 25 = 7x - 1, and

25 = 2x - 1, and so 2x = 26 and x = 13
