The width of the rectangular room is 5 m and the length is 4 m.

The width of the rectangular room is 5 m and the length is 4 m. How much varnish is required to cover the floor in this room if 250 g of varnish are consumed per 1 m2

Since the area is rectangular, we will find its area by the formula for finding the area of a rectangle, that is, multiplying the length by width:

S = 5 * 4 = 20 (m²).

According to the condition of the problem, 250 g of paint is consumed per 1 m² of floor in this room.

Let’s find how much paint is required for the entire area:

20 * 250 = 5000 (g) or 5 kg.

Answer: 5 kg of paint.
