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.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
