the perimeter of a rectangle is
36 cm​

Answer 1

Answer:

let the length of rectangle = l

"     "      breadth "      "        = b

 perimeter of rectangle    = 2(l+b)

   A.T.Q ,

     perimeter of rectangle = 36cm

 so,

                     2(l+b)  = 36              

                      l+b     = 18..... equation (1)
