\underline{\textbf{Given:}}

\textsf{In rectangle ABCD,}

\mathsf{AB=8\;cm\;\&\;BD=10\;cm}

\underline{\textbf{To find:}}

\textsf{Length of AD}

\underline{\textbf{Solution:}}

\mathsf{In\;right\;\triangle\;ABD,}

\textsf{By Pythagoras theorem}

\mathsf{BD^2=AB^2+AD^2}

\mathsf{10^2=8^2+AD^2}

\mathsf{100=64+AD^2}

\mathsf{AD^2=100-64}

\mathsf{AD^2=36}

\mathsf{AD=\sqrt{36}}

\implies\boxed{\mathsf{AD=6\;cm}}

\underline{\textbf{Answer:}}

\textsf{Length of AD is 6 cm}
