a square sandbox has an area of 42 squareft what is the approximate perimeter of the sandbox to the nearest hundredth

Respuesta :

The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
