Question 488781
I'm not sure I understand your question. 
Are you saying that the length and the width of the rectangle are 36 and 25 cm?
If so, then it would be 122 cm.

The formula for the perimeter of a rectangle is :: {{{P = 2l + 2w}}}
l = 36 cm
w = 25 cm

Just plug in the numbers into the equation now.

{{{P = 2*36 + 2*25}}}
{{{P = 72 + 50}}}
{{{P = 122 cm}}}

I hope this helped you :D
