Q. In a square if length of the diagonal is 30cm then side of the square is ________.

$(A C)^{2} = A B^{2} + B C^{2}$
$(30)^{2} = x^{2} + x^{2}$
$2 x^{2} = 900$
$x^{2} = 450$
$x = 3 \times 52$
$= 152$

Q. In a square if length of the diagonal is 30cm then side of the square is ________.

(AC)2=AB2+BC2 (30)2=x2+x2 2x2=900 x2=450 x=3×52​ =152​

$(A C)^{2} = A B^{2} + B C^{2}$
$(30)^{2} = x^{2} + x^{2}$
$2 x^{2} = 900$
$x^{2} = 450$
$x = 3 \times 52$
$= 152$
