Answer:
Answer
Since, The hall is Surrounded by verandah
So, Additional increase in length will be =2∗2.5=5
Similarly , Additional increase in width will be =2∗2.5=5
So Area of Hall + Verandah =(20+5)(15+5)=25∗20=500
and Area of Hall =20∗15=300
Area of verandah =500−300=200
Rate of 1 sq metre =17.5
Rate of 200 sq metre 17.50∗200=3500
