THe cost of renovating a 6 m square room is N540. What is the cost of renovating a 9 m square room?

Answer Details

The cost of renovating a room is directly proportional to the area of the room. If the cost of renovating a 6 m square room is N540, then we can find the cost of renovating a 9 m square room using the proportionality constant. Let C be the cost of renovating a room and A be the area of the room. Then, we have: C = kA where k is the proportionality constant. We can find k by using the given information that the cost of renovating a 6 m square room is N540: 540 = k(6) k = 90 Now, we can use this value of k to find the cost of renovating a 9 m square room: C = kA = 90(9) = N810 Therefore, the cost of renovating a 9 m square room is N810.
