Answer:

Area of rectangle=640m2

        l×b=640      ,length = x

        x×b=640−−−− (i)

    

          Perimeter  = 104

           

          2(x+b)=104

          x+b=52

          b640+b=52        by (i)

        

          640+b2=52b

         b2−52b+640=0

           

         b2−32b−20b+640=0          

         b(b−32)−20(b−32)=0

         (b−32)(b−20)=0

          b=32,20

          x=20,32
