Answer:
   Perimeter of the rectangle  = 6 x +20
   Perimeter of the rectangle  = 0<em> x² + 6 x + 20</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the length of the rectangle = 2x +3
Given that the width of the rectangle = x +7
Perimeter of the rectangle   = 2(length + width)
<u>Step(ii):-</u>             
   Perimeter of the rectangle   = 2(length + width)
                                                   = 2(2 x +3 + x+7)
                                                  =  4x +6+2x+14
                                                  = 6 x +20         
<u><em>Final answer:-</em></u>
  Perimeter of the rectangle  = 6 x +20
   Perimeter of the rectangle  = o x² + 6 x + 20
