Along the perimeter of a rectangular veranda 3m long and 2m wide, a 1m high side is installed; it is necessary to paint the outer side of the side. How much paint is required for this if 90g is consumed per 1 square meter.

1. By the condition of the problem, the sides of a rectangular veranda are 3 m and 2 m each and its height is 1 m.

2. We calculate the total area S of the outer side of all four sides of the side, each of which is a rectangle, by the formula

S is equal to the product of three dimensions:

3 m * 2 m * 1 m * 4 = 24 m².

3. Determine how much paint is required if its consumption rate is 90 g per m²:

90 g / m² * 24 m² = 2160 g = 2.16 kg.

Answer: Paints need 2.16 kilograms.
