Question

A bedroom wall is to be painted around a window as shown below. What is the area of the wall that will be painted? 6 ft 104 ft2 110 ft2 116 ft2

Answer 1

its 108ft

Explanation:

Answer 2

Second option: 104 ft²

Explanation:

The wall and the window are rectangles.

The formula used to calculate the area of a rectangle is:

`A=l*w`

Where "l" is the length and "w" is the width.

Let be
`A_t` the area of the entire wall (including the window),
`A_1` the area of the wall that will be painted and
`A_2` the area of the window.

The area of the wall that will be painted can be calculated by subtracting
`A_t` and
`A_2`.

Then you get:

`A_1=A_t-A_2`

`A_1=(l_t*w_t)-(l_2*w_2)\\\\A_1=(11ft)(10ft)-(3ft)(2ft)\\\\A_1=104ft^2`
