Answer 1

$Given \: Dimensions \: of \: a \: rectangle:$

$Length (l) = 35 \: cm \:and \: breadth (b) = 12\:cm$

$Diagonal (d) = \sqrt{l^{2} + b^{2}}$

$= \sqrt{ 35^{2} + 12^{2}}$

$= \sqrt{1225 + 144 }$

$= \sqrt{ 1369}$

$= 37\: cm$

Therefore.,

$\red{ Diagonal \: of \: the \: rectangle}\green { = 37 \:cm }$
