Step-by-step explanation:

 {(200)}^{2}  = 40000 \: ...(1) \\  {(120)}^{2}  +  {(160)}^{2}  = 14400 + 25600 \\  = 40000 \: ...(2) \\ from \: (1) \: and \: (2) \: we \: have \:  \\  {(200)}^{2}  ={(120)}^{2}  +  {(160)}^{2} \:  \\ hence \: \\  by \: converse \: of \: pythagors \: theorem \\ given \: sides \: make \: a \: right \: triangle \\   length \: of \: perpendicular \: sides \: are \\  \: 120 \: m \: and \: 160 \: m. \\ area \: of \: triangle \:  =  \frac{1}{2}  \times 120 \times 160 \\  = 9600 \:  {m}^{2}  \\ total \: cost \: of \: flooring \:  = 9600 \times  \frac{25}{100}  \\  = 96 \times 25 = Rs \: 2400
