Answer:
4,480
Step-by-step explanation:
In the above question, we are told that the measurements of the stained glass windows Maria intends to make is 14 inches wide by 20 inches long.
Step 1
We find the area of the window
Length × Width ( Breadth)
= 20 × 14 = 280 square inches
Step 2
The tiles that she intends to use has the following measurements
1/4 inch by 1/4 inch
The Area of these glass tiles = 1/4 × 1/4 = 1/16 square inches.
Step 3
Finally to calculate the number of tiles that she would required to make the stained glass window =
Area of the window ÷ Area of the glass tiles
= 280 square inches ÷ 1/16 square inches
= 4,480
Therefore, Maria would be needing 4,480 glass tiles to make her stained glass window.
