The ratio of the corresponding sides of two similar triangles is $3:4$. The ratio of their areas is

Length of a rectangle is twice of its breadth. Area of the rectangle is $18 \, m^2$. What would be its perimeter? (in $m$)

The perimeter of a circle is equal to that of a square. Compare their areas.

If an equilateral triangle of area $X$ and a square of area $Y$ have the same perimeter,then $X$ is

$3$ horses are tethered at $3$ corners of a triangular plot of land having sides $20 \, m$,$30 \, m$,and $40 \, m$,each with a rope of length $7 \, m$. The area (in $m^2$) of the region of this plot,which can be grazed by the horses,is (Use $\pi = \frac{22}{7}$)

The ratio of bases of two triangles is $x: y$ and that of their areas is $a: b$. Then the ratio of their corresponding altitudes will be
