The diagonal is about 16.97 inches long.

The diagonal is 33.941 units.

The diagonal is 14.142 feet.

Use Pythagoras. The diagonal, and two sides of the square form a right angled triangle. So if each side of the square is x cm long, the diagonal is x*sqrt(2) cm long.

A square with a 30-inch diagonal measurement has sides of 21.21 inches in length.

The diagonal of the garden is 20 meters.

The garden's diagonal is 10 meters.

If you take the square of the long side and add it to the square of the short side, you get the diagonal (hypotenuse) squared. Then just find square root of that. For example, if short side is 3cm and long side is 4cm: 9 + 16 = 25, so the diagonal would be the square root of 25 ie. 5.

The diagonal of a square is not perpendicular to its side. The diagonal of a square will separate the square into two triangles. The diagonal goes from one corner to the opposite corner. Because it is a square, the diagonal and a side of the square will always form a 45-degree angle.

Each of them is 14.14 inches long. (rounded)

Use Pythagoras: Diagonal² = √(2 × sidelength²) → diagonal = side_length × √2 → diagonal = 20 × √2 ≈ 28.3 units

A parallelogram is anything from a square to a rectangle. As long as it has parallel sides, then it is a parallelogram. If you're thinking of a rhombus, then it has diagonal sides.

As a square has right angles, the diagonal forms a right triangle with two of the sides of the square. Therefore use Pythagoras: diagonal² = side² + side² → diagonal² = 2side² → diagonal = side × √2 Therefore to find the length of the diagonal of a square, multiply the side length of a square by the square root of 2.

They came from geometry. If you have a square whose sides are 1 unit long then its diagonal is sqrt(2) units long.

14 The ratio of the side of a square to the diagonal is 1.4.

The diagonal of a 5 foot square is about 7.07 feet.

The diagonal of a 101 inch square is about 142.84 inches.

The diagonal measurement of an 8 ft square is: 11.31 feet.

14.142 cm (rounded)

The area is 12.5 m2

Using Pythagoras' theorem: 21.21320344 cm

It is 10 metres.

Not always, the diagonal can be figured out using the Pythagorean Theorem (a²+b²=c²). Where the diagonal is the hypotenuse (c). By rearranging the Pythagorean Theorem, you can see that the diagonal of a square is always 1.4 times the side of the square.
