Calculate the area of the shaded region in each of the figures given below.

Length and Breadth of a rectangular garden are $35 \text{m}$ and $25 \text{m}$, respectively. There is a path $1.5 \text{m}$ wide all around the garden. Find the area of the path.

Through a rectangular field of length $90 \text{m}$ and breadth $60 \text{m}$, two roads are constructed which are parallel to the sides and cut each other at right angles through the centre of the field. If the width of the road is $3\text{ m}$, find 

(i) the area covered by the roads.
