To find the perimeter of the rectangle, we need to add up all four sides.
The length is given as 72–√ cm and the width is given as 5–√ cm.
The two opposite sides will each have a length of 72–√ cm and the other two opposite sides will each have a length of 5–√ cm.
So, the perimeter will be (72–√ + 72–√ + 5–√ + 5–√) cm.
Simplifying this expression, we get 142–√ + 10–√ cm.
Therefore, the correct answer is 142–√+25−−√ cm.
