The diagonal of a square field measures $50 \, m$. The area of the square field is.........$m^2$?

$A$ plot of land is in the shape of a right-angled isosceles triangle. The length of the hypotenuse is $50 \sqrt{2} \text{ m}$. The cost of fencing is ₹$3$ per metre. The total cost of fencing the plot will be

$A$ rectangular plot is $180 \, m^2$ in area. If its length is $18 \, m$,then its perimeter is ...... $m$?

The length and breadth of a rectangular piece of land are in the ratio $5:3$. The owner spent ₹ $6000$ for fencing it from all sides at the rate of ₹ $7.50$ per metre. The difference between its length and breadth is (in metres):

In a shower,$10\, cm$ of rain falls. What will be the volume of water that falls on $1$ hectare area of ground? (in $m^3$)

If the area of a triangle is $150 \, m^{2}$ and the ratio of the base and the height is $3:4$,then find its height in $m$.
