The length of the rectangular room is 6m, the width is 2m less. To varnish the floor in this room, you will need 2kg400g of varnish. What is the consumption of varnish per square meter?

Let’s find first what dimensions the room has. Its width will be:

1) 6 – 2 = 4 (m).

Let’s find the area of the entire floor in this room:

2) 6 * 4 = 24 (m2).

If 2 kg 400 g is consumed on the entire surface, which is also equal to 2400 g (since 1 kg = 1000 g), then we find the consumption per 1 m2:

3) 2400/24 = 100 (g).

Answer: 100 g of paint is consumed per square meter.
