Answer: Areas = 139m²
Cost = Rs3475
Step-by-step explanation:
Area of a square wall of xm= xm².The area of the 4 walls = 4x²m²
Therefore, since the height = 6m, the other side = 6m, the area = 6x6=36m².
Area of the Four walls = 36m²x 4
= 144m². Biu the areas of the four walls excluding the door and window. Area of the door = 2m x 1m= 2m², and area of the window = 3m x 1m = 3m². Total area of the door and window = 2m² + 3m² = 5m².
Therefore, the total area of the four walls excluding the door and window = 144m² - 5m²
= 139m².
The amount required to carpeting the room will be
Let the number of square room carpeted at Rs25 which equals Rs8100 = xm²
Therefore, to know the number of square covered by this amount,= Rs8100/Rs25 = 324m²
If 324m² = Rs8100
1m² = 8100/324
139m²= 8100/324 x 139
= Rs3475
