The diagonal of a square is x what is the perimeter of the square
RSB [31]

Answer:

2\sqrt{2} x

Step-by-step explanation:

The diagonal divides the square into 2 right angles with legs s and hypotenuse x

Using Pythagoras' identity on one of the right triangles, then

s² + s² = x²

2s² = x² ( divide both sides by 2 )

s² = \frac{x^2}{2} ( take the square root of both sides )

s = \sqrt{\frac{x^2}{2} } = \frac{x}{\sqrt{2} }

Thus

perimeter = 4s = 4 × \frac{x}{\sqrt{2} } = \frac{4x}{\sqrt{2} }

Multiply numerator/ denominator by \sqrt{2}

perimeter = \frac{4x\sqrt{2} }{2} = 2\sqrt{2} x
