Answers (1)

We have,
Length and breadth of a photograph is 32 cm and 21 cm respectively.

So, According to question,
Length of wooden strip required to frame the photograph = 2 [L + B]
                                                                                            = 2 [32 + 21] cm
                                                                                            = 2 \times  53 cm  = 106 cm

Hence the required length of the strip is 106 cm or 1.06 m
