The length of a rectangle is (x+22. The width of the rectangle is (x^2+1). Which expression represents the perimeter of the rectangle?

Respuesta :

Hi

Perimeter is the sum of all sides of the rectangle.

It have  2  width

            2 length   ( x²+1)  

So :   one  width  is     (x+22)   so 2  is   2 * (x+22)

                 length  is   (x²+1)     so 2 is  2* (  x²+1)

So perimeter is  :   2 (x+22) + 2 (x²+1)

                                 2 ( x+22 +x²+1)

                                 2 ( x²+x+23)

perimeter is :  2x² +2x+ 46
