Given,

Length of Hall = 20m

Breadth of Hall = 15m

The hall was surrounded by a verandah of width 2.5m

Since, The hall is Surrounded by verandah 

So, Additional increase in length will be

 2 \times 2.5 = 5m

Now,

Total Area = Area of Hall + Verandah

\boxed {\bf{Area\;of\; Rectangle = l×b}}

(20+5)(15+5)

25\times20

\boxed {500 m²}

Area of Hall = l×b

20\times15

\boxed {300m²}

Area of Verandah = Area of Total Room - Area of Hall

 500m²-300m²

200m²

Area of Verandah = \fbox\red {200m²}

Rate of 1 sq.mt for flooring = Rs. 3.50

Rate of 200 m² = 200 × 3.50

\Large\purple {Rs.700}

Hope It Helps You ✌️
