Answer 1

1 - 384msquare
2- rs.9600

Answer 2

Answer:

The area of verandah is 384 sq.m.

The total cost is Rs.9600.

Step-by-step explanation:

Length of hall = 25 m

Width of hall = 15 m

Width of verandah = 4 m

Length of Verandah including hall = 25+4+4 =33 m

Width of Verandah including hall = 15+4+4 =23 m

Area of verandah = Outer area - Inner Area

                             $=(33 \times 23)-(25 \times 15)$

                             $=384 m^2$

Hence the area of verandah is 384 sq.m.

Cost of flooring 1 sq.m. = Rs.25

Cost of flooring 384 sq.m. = $25 \times 384$

                                           = $9600$

Hence the total cost is Rs.9600.
