The area of a square photo frame is 250 cm.
find the perimeter of the photo frame, leaving
your answer correct to 1 decimal place.

Step-by-step explanation:

The area of a square can be calculated with the following formula:

Where "s" is the lenght of each side.

If you solve for "s":

According to the information provided in the exercise, the area of the square photo frame is:

Knowing its area, you can substitute it into  and evaluate in order to find "s":

Since the perimeter of a figure is the sum of the lenght of its side and the all four sides of a square are equal, you get that its perimeter is:

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
