What is the length of the wooden strip required to frame a photograph of length and breadth 32 cm and 21 cm respectively?
Length of wooden strip = Perimeter of photograph
Perimeter of photograph = 2 x (length + breadth)
= 2 (32 + 21)
= 2 x 53 cm
= 106 cm
Thus, the length of the wooden strip required is equal to 106 cm.
