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

Answer:

Given, length of the wooden strip = 32 cm and breadth of the wooden strip = 21 cm Now, wooden strip required = Perimeter of the photograph \[=2\times \](Length + Breadth) \[=2\times (32\,cm+21\,cm)\] \[=2\times 53\,cm=106\text{ }cm\] Hence, the required length of wooden strip is 106 cm.
