Question 2
Suresh has a ribbon of length 78 cm. He wants to apply it on the edges of a rectangular photo frame of length 26 cm. Find the breadth of frame.

Answer 1

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 .
