A Correct answer
Explanation
Total cost of cultivation$=$Rs.$680$
Cost per hectare$=$Rs. $170$
$\therefore $Area of cultivation$=\cfrac { 680 }{ 170 } =4$ hectare$=4\times { 10 }^{ 4 }m^2$
Now, field's shape is square, therefore area $=side \times side$
$\Rightarrow 4\times { 10 }^{ 4 }={ (side) }^{ 2 }$
$\Rightarrow $ side$=\sqrt { 4\times { 10 }^{ 4 } } =200m$
Perimeter of field$=4\times 200=800m$
$\therefore $ Cost of fencing $800m=$ Rs.$\left( 3\times 800 \right) =$ Rs.$2400$

  4. ${\rm{1}}{{\rm{0}}^{ - 3}}\,{\rm{kg/c}}{{\rm{m}}^{\rm{3}}}$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

We have,

$1\ g/cm^3$

Since,
$1000\ g=1\ kg$
$1\ g=10^{-3} \ kg$

So,

$1\ g/cm^3 =10^{-3}\ kg/cm^3$

Hence, this is the answer.
