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
<span>Equilateral triangles have sides of all equal length and angles of 60°. To find the area, we can first find the height. To find the height, we can draw an altitude to one of the sides in order to split the triangle into two equal 30-60-90 triangles.</span>
