Answer:

450 rs

Step-by-step explanation:

Area of room = 4 × 5.5

= 22 m²

Area of verandah with room =

= ( 5.5 + 1.25 + 1.25 ) × ( 4 + 1.25 + 1.25 )

= 8 × 6.5

= 52 m²

Area of verandah = ( 52 - 22 ) m²

= 30 m²

Cost of cementing the floor of verandah = 15rs/m²

Total cost of cementing 30 m²= 30 × 15

= 450 rs
