Question

Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area. There is a window in the middle of the wall, so he'll only need to paint the shaded part shown. How many square feet is just the window? [Note: The wall and window are both rectangular.]

Answer 1

Answer:

Area of window = 3 ft²

Area to be painted = 45 ft²

Explanation:

To get the area to be painted, we will start by getting the area of the whole wall (including the window), then subtract from it the area of the window

1- getting area of whole wall:

From the figure, we can note that the length and width of the wall are given as 6 ft and 8 ft

Area of whole wall = length * width

Area of whole wall = 6 * 8 = 48 ft²

2- getting area of window:

Again, from the figure, we can note that the length and width of the window are 2 ft and 18 in (which is equivalent to 1.5 ft)

Area of window = length * width

Area of window = 2 * 1.5 = 3 ft²

3- getting area to be painted:

Area to be painted = area of whole wall - area of window

Area to be painted = 48 - 3 = 45 ft²

Hope this helps :)
