The length and breadth of a room are 6m by 4m. How many square metres of carpets are required to completely cover the floor of the room? If the carpet cost ₹240 per square metre, how much will it cost to cover the entire room?
Answers
Length, l = 6 m
Breadth, b = 4 m
Area = lb
= Length × Breadth
= ( 6 × 4 ) sq.m
= 24 sq.m
Cost of 1 sq.m of carpet = ₹240
Cost of 24 sq.m of carpet = 24 × ₹240
= ₹5760
Answer:
Total cost of the carpet for completely covering the floor of the room is ₹5760.
Step-by-step explanation:
Given that, the length and breadth of a room are 6m and 4m respectively. The cost of the carpet of per square metre is ₹240.
With this information, we are asked to find the total cost of the carpet for completely covering the floor of the room.
We know, floor is in the shape/form of a rectangle. The area of a rectangle of length l and breadth b is given by,
→ Area of rectangle = l * b
By substituting the given values in the formula, we get the following results:
→ Area of floor = 6 * 4
→ Area of floor = 24m²
Now, cost of carpet = Cost of carpet of per square metre * Area of the floor
→ Cost of carpet = 240 * 24
→ Cost of carpet = ₹5760
Hence, total cost of the carpet for completely covering the floor of the room is ₹5760.
