Answer 1

Answer:

$\sf \: As \: we \: know \: that \: if \: we \: want \: to \: \\ \sf find \: the \: diagonal \: of \: rectangle \\ \sf \: we \: use \: this \: formula : \\ \\ \implies \red{ \sqrt{ {l}^{2} + {b}^{2} }} \\ \\ \sf \: so \: here \: length \: is \: 40m \: and \: breath \: is \: 7 \\ \\ \sf \: so \: diagonal \: of \: rectangle = \sqrt{ {l}^{2} + {b}^{2} } \\ \\ \implies \: \sqrt{ {40}^{2} + {9}^{2}} \\ \\ \implies \sqrt{1600 + 81} \\ \\ \: \implies \: \sqrt{1681} \\ \\ \implies \underline{ \boxed{ \green{ \sf \: 41 \: m}}}$
