Answers
Answer:
Rs. 124.80 will be the cost of coloring 2 windows and 1 door.
Step-by-step explanation:
Dimensions of the door = 2 m × 1.4 m
Therefore, the area of the door = 2.8m²
Dimensions of the window = 1.3m × 1.2m
Therefore, the area of the window = 1.56m²
We need to calculate the cost to colour 2 windows and 1 door.
Area of two windows = 1.56m² × 2 = 3.12m²
We know Cost = Rate × Area
=> Cost = 40 × 3.12m²
=> = Rs. 124.80
Therefore, Rs. 124.80 will be the cost of coloring 2 windows and 1 door.
Answer:
Total cost will be 236.8 rupees.
Step-by-step explanation:
There are one door and two windows in the room.
Length and breadth of the door is 2 meters and 1.4 meters respectively.
Then , the area of the door is ( 2 × 1.4 ) = 2.8 m²
Length and breadth of the windows are 1.3 meters and 1.2 meters respectively.
Then , the total area of the two windows is ( 2 × 1.3 × 1.2 ) = 3.12 m²
∴ The total area for coloring is ( 2.8 + 3.12 ) = 5.92 m²
∴ The total cost is ( 40 × 5.92 ) = 236.8 rupees.
