Solutions :

Area of 4 walls of a room = 2 (l + b) × h

Area of floor = l × b

Floor Area of bedroom = 15 × 12 × 2 = 360 m2

Floor Area of drawing room = 20 × 18 = 360 m2

Floor Area of Dining room = 64 m2

Floor Area of Kitchen room = 120 m2

Floor Area of Bathroom = 48 m2

So, Total = 952 m2

Remaining area = 1000 – 952 = 48 m2

Cost of carpeting = 48 × 16 = Rs. 768

Room	Area	Cost
2 Bedrooms	2x(2(15+12)×15)=810×2=1620	81000
Drawing	2(20+18)×15=1140	57000
Dining	2(8+8)×15=480	24000
Kitchen	2(10+12)×15=660	23100
Bathroom	2(8+6)×15=420	14700
