Answer 1

Let's draw the scenario to better understand the problem:

To be able to determine the area that is not covered by the pictures, we will be using the following formula:

`\text{ Area}_{Not\text{ Covered}}\text{ = Total area of the cardboard - Total area of the pictures}`

We get,

`\text{ Area}_{Not\text{ Covered}}\text{ = Total area of the cardboard - Total area of the pictures}`
`\text{ = (20 x 9) - 3(7 x 4)}`
`\text{ = 180 - 3(28)}`
`\text{ = 180 - 84}`
`\text{Area}_{Not\text{ Covered}}=96in^2`

Therefore, the area that is not covered is 96 in^2.
