Question

What is the length of the wooden strip required to frame a photograph of length and breadth $32\mathrm{cm}$ and $21\mathrm{cm}$ respectively?

Answer 1

Find the length of the wooden strip.

Given

The length of the photo frame is $32$

The breadth of the photo frame is$21$

The Perimeter of the rectangular photograph is as follows:

$\begin{array}{rcl}\mathrm{Perimeter}& =& 2(\mathrm{Length}+\mathrm{Breadth})\\ & =& 2\left(32+21\right)\\ & =& 2\left(53\right)\\ & =& 2\times 53\\ & =& 106\mathrm{cm}\end{array}$

Hence, the length of the wooden strip is $106cm$.
