See Explanation

Step-by-step explanation:

Given

[tex]1\ can = 2.2m^2[/tex]

Required

Determine the number of cans for the wall

The dimension of the wall is not given. So, I will use the following assumed values:

[tex]Length=20m[/tex]

[tex]Width = 44m[/tex]

First, calculate the area of the wall

[tex]Area = Length * Width[/tex]

[tex]Area = 20m * 44m[/tex]

[tex]Area = 880m^2[/tex]

If [tex]1\ can = 2.2m^2[/tex]

Then [tex]x = 880m^2[/tex]

Cross Multiply:

[tex]x * 2.2m^2 = 1 * 880m^2[/tex]

[tex]x * 2.2m^2 = 880m^2[/tex]

[tex]x * 2.2 = 880[/tex]

Make x the subject

[tex]x = \frac{880}{2.2}[/tex]

[tex]x = 400[/tex]

400 cans using the assume dimensions.

So, all you need to to is, get the original values and follow the same steps
