If Suresh has a ribbon of length 78 cm and he applies it on the edges of a rectangular photo frame of length 26 cm , then the breadth is 13 cm.

  • Let the length be 26 cm and the breadth be b. Perimeter of the rectangle is 2( 26 + b ) = 52 + 2b.
  • Given the perimeter is 78 cm, 78 = 52 + 2b
  • ⇒ 2b = 78 -52 ⇒ b = 26 / 2 = 13 cm .
