Question

What is the length of the wooden strip required to frame a photograph of length and breadth 32 cm and 21 cm respectively?

Answer 1

\(\text{Length of wooden strip} = \text{Perimeter of photograph}\)
\(\text{ Perimeter of photograph }\)= \(2 \times (length + breadth)\) 
= \(2 (32 + 21) \)
= \(2 \times 53\) \(cm\) 
= \(106\) \(cm\)

Thus, the length of the wooden strip required is equal to \(106\) \(cm\).
