ANSWER:

From the question it is given that,

Side of square garden (s) = 30 m

Then,

Area of the square garden = S2

= 302

= 30 × 30

= 900 m2

From the figure,

The new side of the square garden when path is not included is 28 m.

New area of the room when verandah is included = 282

= 28 × 28

= 784 m2

The area of path = Area of the square garden when path is included – Area of the square Garden when path is not included

= 900 – 784

= 116 m2
