Hans Raj 7 years, 8 months ago

$\sqrt{}$ 367

$\sqrt{}$ 361 = 19

$\sqrt{400}$ = 20

so $\sqrt{367}$ is between > 19 and < 20

$\sqrt{367}$ = $\sqrt{}$ 19.157 x 19.157

$\sqrt{367}$ = 19.157

s = ${{a + a + b} \over 2} = {{2a + b} \over 2}$

Now, Area of triangle = $\sqrt {s\left( {s - a} \right)\left( {s - b} \right)\left( {s - c} \right)}$

= $\sqrt {{{2a + b} \over 2}\left( {{{2a + b} \over 2} - a} \right)\left( {{{2a + b} \over 2} - a} \right)\left( {{{2a + b} \over 2} - b} \right)}$

= $\sqrt {{{2a + b} \over 2}\left( {{{2a + b - 2a} \over 2}} \right)\left( {{{2a + b - 2a} \over 2}} \right)\left( {{{2a + b - 2b} \over 2}} \right)}$

= $\sqrt {{{2a + b} \over 2}\left( {{b \over 2}} \right)\left( {{b \over 2}} \right)\left( {{{2a - b} \over 2}} \right)}$

= $\sqrt {{{4{a^2} - {b^2}} \over 4}{{\left( {{b \over 2}} \right)}^2}}$

= ${b \over 4}\sqrt {4{a^2} - {b^2}}$

$8{a^3} + {b^3} + 12{a^2}b + 6a{b^2}$

= ${\left( {2a} \right)^3} + {\left( b \right)^3} + 3{\left( {2a} \right)^2}\left( b \right) + 3\left( {2a} \right){\left( b \right)^2}$
