# Find the length of the side of a square whose area is 441 m^{2}

**Solution:**

We know that,

Area of the square = side of a square × side of a square

Since the area of a square is equal to the square of its side., the length of the side can be calculated by finding the square root of the area.

441 m^{2} = (side of a square)^{2}

Side of a square = √441 = 21 m

The length of the side of a square whose area is 441 m^{2 }is 21 m
