Following is a figure of a rectangular park whose length is $30 \mathrm{m}$ and width is $20 \mathrm{m}$.

What is the total length of the fence surrounding it? (Write answer in $\mathrm{m}$)

Following is a figure of a rectangular park whose length is $30 \mathrm{m}$ and width is $20 \mathrm{m}$.

If $k {\mathrm{m}}^2$ land is occupied by the park then find $k$.

There is a path of one-metre width running inside along the perimeter of the park that has to be cemented. If $1$ bag of cement is required to cement $4 {\mathrm{m}}^2$ area, if $k$ bags of cement would be required to construct the cemented path, find the value of $k$?

There are two rectangular flower beds of size $1.5 \mathrm{m}\times 2 \mathrm{m}$ each in the park as shown in the given diagram and the rest has grass on it. If the area covered by grass is $k {\mathrm{m}}^2$, find the value of $k$.
