Question
Find the diagonal of a rectangle whose length is $35 cm$ and breadth is $12\ cm.$
✓
Answer
The diagonal $=\sqrt{ }\left[\right.$ length ${ }^2+$ breadth $\left.^2\right]$
$=\sqrt{ }\left(35^2+12^2\right)$
$=\sqrt{ }(1225+144)$
$=\sqrt{ } 1369$
$=37$
Thus the diagonal is $37\ cm .$
$=\sqrt{ }\left(35^2+12^2\right)$
$=\sqrt{ }(1225+144)$
$=\sqrt{ } 1369$
$=37$
Thus the diagonal is $37\ cm .$
