Answer: The drapes have to be 5 5/12 long.
Explanation:
Hi, to solve this problem we have to analyze the information:
Wall beneath the window: 2 2/3 feet
Window: 2 3/4 feet
Now, to obtain the length of the drapes we simply have to sum the length of the window and the length of the wall beneath the window.
So, mathematically speaking:
2 2/3= 8/3
2 3/4=11/4
8/3 + 11/4 = 32/12+ 33/12= 65/12
65/12= 5 5/12
The drapes have to be 5 5/12 long.
