Question

The diagonal of a square has a length of 10 cm. Find the length of a side of the square.

Answer 1

@manguitar
diagonal of square = sqrt(2) * Side of square
plug in the value of diagonal and then u will get your side

Answer 2

could you explain a litttle bit more?

Answer 3

Let us assume side of square be 'a'
in order to determine d (diagonal) , we used pythagoras theorem
\[d^2 = a^2+a^2\]
\[d^2 = 2a2\]
\[d = \sqrt(2) * a\]
where a = side of square and d = diagonal of square
