A) 32 cms
B) 28 cms.
C) 56 cms.
D) Cannot be determined
E) None of these
Correct Answer: B
Solution :
Length of the rectangle \[=\sqrt{Diagona{{l}^{2}}-\text{ }breadt{{h}^{2}}}\] \[=\sqrt{{{10}^{2}}-{{6}^{2}}}=\sqrt{100-36}=\sqrt{64}=8\,cm\] \[\therefore \]Perimeter of the rectangle = 2 (Length + breadh) \[=2\left( 8\text{ }+6 \right)=28\text{ }cm\]
