Answer:

P = 63.87 in

Explanation:

area of a square window = 255 in²

find perimeter of the window.

A = s²

255 = s²

s = 15.97 in.

perimeter = 4 * s

P = 4 (15.97)

P = 63.87 in

Answer:

If you meant the area was 255 in²:

Perimeter is
4√(255), or around 63.89 in.

If you meant that the area was 225 in²:

Perimeter is 60 in

Explanation:

If you meant the area was 255 in²:

If we have a square with an area of 255 in², then it's side length will be
√(255) inches long, since the area of a square is
l^2, where l is the length.

Since
√(255) doesn't return a rational number, we'll leave it as
√(255).

Now that we know the side length, the perimeter of a square is represented as
4l, where l is the length.

We know the length is
√(255), so we can multiply this by 4.


4√(255). This is the simplest it gets.

If you meant the area was 225 in²:

Following the same concept as again:

Length:
√(225) = 15

Perimeter:
4\cdot15=60 in

Hope this helped!
