$A$ lawn is in the form of a rectangle having its breadth and length in the ratio $3:4$. The area of the lawn is $\frac{1}{12}$ hectare. The breadth of the lawn is..........$metres$.

$A$ person $A$ takes $15 \text{ seconds}$ to cross a rectangular field diagonally walking at a speed of $52 \text{ m/min}$. $A$ person $B$ takes the same time to cross the same field along its sides (length + width) walking at a speed of $68 \text{ m/min}$. The area of the field is $....... \text{ m}^2$.

If the ratio of areas of two circles is $4:9,$ then the ratio of their circumferences will be

Find the perimeter of a circular plot which occupies an area of $154 \, m^{2}$ (in $m$).

What is the cost of flooring a rectangular hall?
Statements:
$I.$ The length of the rectangle is $6 \ m$.
$II.$ The breadth of the rectangle is $2/3$ of its length.
$III.$ The cost of flooring an area of $1 \ m^2$ is ₹ $4500$. (Note: Corrected unit/value for logical consistency).

The ratio of length and breadth of a rectangular plot is $8:5$ respectively. If the breadth is $60\, m$ less than the length,what is the perimeter of the rectangular plot? (in $m$)
