James is painting his 10 by 8 foot bedroom wall that contains a 2 by 3 foot window. How many square feet of wall does he need to paint
(10 * 8) - 6 = _______ square feet
I still dont get this even when she just explained it I need so some help with this question.
The answer is 74 square foot, because 10 multiplied by 8 equals to 80, 3 multiplied by 2 equals 6. 80 minus 6 equals to 74 square foot. So James has to paint 74 square foot.
To find out how many square feet of wall James needs to paint, we first calculate the total area of the wall and then subtract the area occupied by the window.
The area of a rectangular wall is calculated by multiplying its length by its height. In this case, the length of the wall is 10 feet and the height is 8 feet, so the total area of the wall is:
10 feet * 8 feet = 80 square feet.
Next, we need to determine the area of the window. The window is 2 feet by 3 feet, so its area is:
2 feet * 3 feet = 6 square feet.
Finally, to find the area of the wall that needs to be painted, we subtract the area of the window from the total area of the wall:
Total area of the wall - Area of the window = 80 square feet - 6 square feet = 74 square feet.
Therefore, James needs to paint 74 square feet of wall.
