A rectangular room is 4.6 m long and 3.7 m wide. How much to the nearest kobo will it cost to carpet the room if carpet costs N500.75 per square metre?
Answer (1)
To calculate the cost of carpeting the room, let's follow these steps:
Calculate the Area of the Room:
The room is rectangular, and the formula to find the area of a rectangle is Area = Length × Width .
Given that the length is 4.6 m and the width is 3.7 m, the area of the room can be calculated as follows: Area = 4.6 × 3.7 = 17.02 square meters .
Calculate the Cost to Carpet the Room:
The cost of the carpet per square meter is given as N 500.75 .
Therefore, the total cost to carpet the room is: Total Cost = Area × Cost per Square Meter = 17.02 × 500.75.
Simplifying this: Total Cost = 8 , 521.765.
Rounding to the Nearest Kobo:
Since 1 Naira is divided into 100 kobo, you can consider the value after the decimal point as kobos. Here, the value is 765 kobos, which is 76.5 kobo after conversion.
If you round 76.5 to the nearest kobo, you get 77 kobo.
Therefore, the total cost, rounded to the nearest kobo, is N 8 , 521.77 .
So, to the nearest kobo, it will cost N 8 , 521.77 to carpet the room.
