Q.9. The side of a square is 25 cm. Find the length of its diagonal correct to 2 decimal places.

$A{C}^{2}=A{B}^{2}+B{C}^{2}\phantom{\rule{0ex}{0ex}}\Rightarrow A{C}^{2}={25}^{2}+{25}^{2}\phantom{\rule{0ex}{0ex}}\Rightarrow A{C}^{2}=625+625\phantom{\rule{0ex}{0ex}}\Rightarrow A{C}^{2}=1250\phantom{\rule{0ex}{0ex}}\Rightarrow AC=35.35$
