Answer 2

Answer:

Perimeter of the photo frame is 63.2 cm.                        

Step-by-step explanation:

Given : The area of a square photo frame is 250 cm².

To find : The perimeter of photo frame?

Solution :

The area of a square photo frame is 250 cm².

The area of the square is

$A=s^2$

$250=s^2$

$s=\sqrt{250}$

$s=15.8$

The side of the square is 15.8 cm.

The perimeter of the square is $P=4s$

$P=4\times 15.8$

$P=63.2cm$

Therefore, Perimeter of the photo frame is 63.2 cm.
