Answer 1

Answer:

Rs 1387.50

Step-by-step explanation:

Find the dimension of the room with the verandah:

Length = 7.5 + 2.5 + 2.5 = 12.5 m

Breadth = 6 + 2.5 + 2.5 = 11 m

Find the area of of the room with the verandah:

Area = Length x Breadth

Area = 12.5 x 11 = 137.5 m²

Find the area of the room:

Area = Length x Breadth

Area = 7.5 x 6 = 45 m²

Find the area of the verandah:

Area = 137.5 - 45 = 92.5 m²

Find the cost:

1 m² = Rs 15

92.5 m² = 15 x 92.5 = Rs 1387.50

Answer: The cost is Rs 1387.50
