1 thought on “the perimeter of a rectangle is 40 cm the length is 1 less than twice the width of the rectangle find its length and breadth​”

1. Step-by-step explanation:

   Let the breath be x

   2(l+b) = 40 cm

   2( 2x-1 + x ) = 40 cm

   6x – 2 = 40 cm

   6x = 42 cm

   x = 42/6 cm

   x = 7 cm

   ∴ The breath is 7 cm, and

   the length is 13 cm
