It costs 37800 to cover the floor of a room of length 12m and width 10.5 with a straw mat. What was the cost per msquare of the straw mat

The area of the room is:

12m x 10.5m = 126m²

The cost per square meter of the straw mat is:

37800 / 126 = 300

Therefore, the cost per square meter of the straw mat is 300.

To find the cost per square meter of the straw mat, we need to divide the total cost by the area of the room.

First, let's calculate the area of the room:
Area = length x width = 12m x 10.5m = 126m²

Next, divide the total cost by the area of the room:
Cost per square meter = Total cost / Area
Cost per square meter = 37800 / 126 = 300

Therefore, the cost per square meter of the straw mat is 300.
