A wall in Marcus's bedroom is 8 1/3 feet high and 16 1/5 feet long. If he paints 1/3 of the wall blue, how many square feet will be blue?
Answer:
45 ft² will be blue
Explanation:
1- getting the area of the wall:
area of the rectangle can be calculated as follows:
area = length width
we are given that:
length = \(16 \frac{1}{5}\) ft
width = \(8 \frac{1}{3}\) ft
Now, substituting in the above rule, we can get the area as follows:
area = \(16 \frac{1}{5}\) \(8 \frac{1}{3}\) = 135 ft²
2- getting the area that would be pained blue:
We are given that \(\frac{1}{3}\) of the area of the room would be painted blue, this means that:
area of blue = \(\frac{1}{3}\) area of room
area of blue = \(\frac{1}{3}\) 135
area of room = 45 ft²
Hope this helps :)
