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 $106$ $cm$.
