An artist made a stained-glass window that is 3 1/2 feet by 2 3/4 feet.
a) what is the area of the window? (solved. it's 9 5/8 square feet.
b) the artist's design used squares of colored glass that measure 1/4 foot by 1/4 foot long how many colored squares did the artist use?
(show work on paper and send it to me or explain)

The stained-glass window is 3 1/2 feet by 2 3/4 feet.
For the item#1, solving for the area:
Area = (3 1/2 feet) x (2 3/4 feet)
Area = 9/4 feet or 2.25 feet²

For the item#2, solve for the area of the colored glass:
Area colored glass = (1/4 foot) x (1/4 foot)
Area colored glass = 1/16 feet² or 0.0625 feet²

Solving for the total numbers of colored squares:
Total numbers = 2.25 / 0.0625
Total numbers = 36

The total numbers of colored square is 36 pieces.
