Question

Kierston needs to paint a wall of the youth center. She knows that 1 can of paint covers an area of 2.2 square meters. Kierston measures the wall using a meter stick as shown below. How many cans of paint must kierston buy to paint the wall of the youth center?

Answer 1

See Explanation

Explanation:

Given

`1\ can = 2.2m^2`

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:

`Length=20m`

`Width = 44m`

First, calculate the area of the wall

`Area = Length * Width`

`Area = 20m * 44m`

`Area = 880m^2`

If
`1\ can = 2.2m^2`

Then
`x = 880m^2`

Cross Multiply:

`x * 2.2m^2 = 1 * 880m^2`

`x * 2.2m^2 = 880m^2`

`x * 2.2 = 880`

Make x the subject

`x = (880)/(2.2)`

`x = 400`

400 cans using the assume dimensions.

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