Application of perimeters and area

The length of a guava garden is $180$m and breadth $120$m. There are two paths $3$m wide in the middle of the garden cutting each other at right angles. If the value of cost of earthing up the road at the rate of  $₹12.0$per metre in rupees is $k,$ then find the value of $k$?

If the value of area of the part in the figure which is not shaded is $a,$ then find the value of $a$?

The length of a rectangular courtyard is $6$ m and the breadth is $5$m. In the middle of it, two roads $2$meters wide are situated in such a way that each cuts each other at right angles. One is parallel to the length of the road and the other is parallel to the width of the road. If the cost of paving the road at the rate of Rs $2.50$per square metre. is $₹a.$ Find the value of $a$?

If the area of the shaded region of the given figure is $k$, then find the value of $\text{'}k\text{'}$?

The length of a hall is $20 \mathrm{m}$ and the width is $8 \mathrm{m}$. Its edges are decorated by marble stone of width $2 \mathrm{m}$.

Make a figure and find the area of the decorated portion in ${\mathrm{m}}^2$.

(Enter only the numerical part of answer. That, is without units)
