Ex 10.1 Class 6 Maths Question 4. What is the length of the wooden strip required to frame a photograph of length and breadth 32 cm and 21 cm respectively?

Solution: Length of the strip = 32 cm Breadth of the strip = 21 cm ∴ Perimeter = 2 [length + breadth] = 2 [32 cm + 21 cm] = 2 x 53 cm = 106 cm Hence, the required length of the strip = 106 cm or 1 m 6 cm.
