Suppose the side of the square is s, then length of diagonal = s*sqrt(2)
s*sqrt(2) = 18
so s = 18/sqrt(2) = 12.7 units.
The diagonal of an 18 inch square is about 25.46 inches. (18 times the square root of 2).
18 ft Diagonal of a square is the square root of 2, times the side.
Diagonal = 18*sqrt(2) = 18*1.414214 = 25.45584 feet
A = 18 square units.
Ah, the diagonal of a square is a special thing indeed. If you have a square that's 18 units on each side, you can use a little math magic to find its diagonal. By using the Pythagorean theorem, you'll see that the diagonal of this square would be 18 times the square root of 2. Just remember, there's always a way to find beauty and harmony in even the most geometric of shapes.
Use Pythagoras' therom: 32+32 = 18 The square root of 18 is 4.242640687 units which is the length of the diagonal.
Side = diagonal/1.5Side = 12Perimeter = 12 * 4Perimeter = 48
A square whose diagonal is the diameter of the circle. So, if it is a circle with diameter 18 units then the diagonal of the square is 18 units and so its side is 9*sqrt(2) = 12.7 units.
The perimeter = 12 feetthen the square diagonal = 12/4 = 3 feet The diagonal2 = 3x3 + 3x3= 18 feetThe diagonal = square root of 18 = 3x 21/2 feet = 3 x 1.4142 = 4.2426 feet
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.
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.
It's the square root of the sum 18 feet squared plus 18 feet squared. 18 feet squared is 324 square feet. 2 x 324 square feet = 648 square feet. The square root of 648 square feet is about 25.46 feet.
