Answer:
Leah requires a curtain of 6.5 feet.
Explanation:
Leah is buying curtains to hang from the top of the window to the floor.
Window is 4 feet high from the bottom of the window and the base of the window is 2.5 feet above the floor.
Therefore Leah will require a curtain with a length = height of the window + height of the base of the window from the floor.
= 4 + 2.5 = 6.5 feet.
So the length of the curtain should be 6.5 feet.
