Answer:

6

Step-by-step explanation:

You have a total area of 2,200 sq units to cover... and each can of paint covers 400 sq units.  So, you'll need:

2200 sq units / 400 sq units/can = 5.5 cans

In such problems, we always round up, since you will need 5 full cans of paint, and half of a 6th can.

So, in total you will need 6 cans of paint to cover all 2,200 sq units.

The cans of paints and areas are illustrations of equivalent ratios.

5.5 cans are needed to paint an area of 2200 units square

The given parameter is:

[tex]\mathbf{Cans : Area = 1 : 400}[/tex]

Express as fraction

[tex]\mathbf{\frac{Cans }{ Area }= \frac{1 }{ 400}}[/tex]

Multiply both sides by Area

[tex]\mathbf{Cans= \frac{1 }{ 400} \times Area}[/tex]

When the area is 2200, we have:

[tex]\mathbf{Cans= \frac{1 }{ 400} \times 2200}[/tex]

[tex]\mathbf{Cans= 5.5}[/tex]

Hence, 5.5 cans are needed to paint an area of 2200 units square
