Is the diagonal of a square equal to its sides?

Answer: No, the diagonal of a square is not equal to its sides. The diagonal of a square is calculated by using the formula: Diagonal of Square (d) = √2 × s, Here ‘s’ is the side of the square.

What is the perimeter and area of square?

Answer: The area of a square is equal to the square of the length of its side and the perimeter of the square is 4 times the length of its side. Let the length of the side of a square be ‘a’ units.

### How to find the perimeter of a square using the diagonal?

Note: Using the diagonal, the perimeter of the square can also be found as explained below. Finding Perimeter of Square Using Diagonal. It is known that the area of a square in terms of diagonal = ½ × d 2. Now, a × a = ½ × d 2. Or, a = √(½ × d 2) As the perimeter of square = 4a, P = 4 × √(d 2 /2) units.

How do you find the perimeter of a swimming pool?

Then the perimeter is simply 2 x 4 = 8 inches. For a real-world example, take a square pool that you need to encompass in rope completely. One side measures 10 meters. To find the perimeter of the square pool just multiply 10 by 4 to get 40 meters.

#### What is the length of the diagonals of the square?

The length of the diagonals of the square is equal to s√2, where s is the side of the square. As we know, the length of the diagonals is equal to each other. Therefore, by Pythagoras theorem, we can say, diagonal is the hypotenuse and the two sides of the triangle formed by diagonal of the square, are perpendicular and base.
