Step-by-step explanation:

\frac{( {( {x}^{3} {x}^{4}  )}^{2}) }{ {( {x}^{5} {x}^{3}  )}^{z} }  =  {x}^{ - 2}  \\  \\  \frac{( {( {x}^{3 + 4}  )}^{2}) }{ {( {x}^{5 + 3} )}^{z} }  =  {x}^{ - 2} \\  \\  \frac{ {(( {x}^{7} ) }^{2}) }{ {( {x}^{8} )}^{z} }  =  {x}^{ - 2}  \\  \\    \frac{ {x}^{7 \times 2} }{ {x}^{8 \times z} }  =  {x}^{ - 2} \\  \\    \frac{ {x}^{14} }{ {x}^{8z} }  =  {x}^{ - 2}  \\  \\  {x}^{14 - 8z}  =  {x}^{ - 2}  \\  \\ 14 - 8z =  - 2 \\  \\ 14 + 2 = 8z \\  \\ 16 = 8z \\  \\ z =  \frac{16}{8}  \\  \\ z = 2

Area = 2√7 × 2√7

⇒ Area = 4 × 7 = 28 inch.
