Answer:
35 square feet
Explanation:
To find the total area of fabric needed for the quilt, we need to add up the areas of the individual fabric pieces.
The area of a square or rectangle can be found by multiplying its length by its width. In this case, we are given the measurements in square yards, so we need to convert them to square feet.
Since 1 yard is equal to 3 feet, we can convert square yards to square feet by squaring the conversion factor: (1 yard * 3 feet/yard)^2 = 9 square feet/yard^2.
For the green fabric: 4 square yards * 9 square feet/yard^2 = 36 square feet.
For the purple fabric: 4 square yards * 9 square feet/yard^2 = 36 square feet.
For the white fabric: 7 square yards * 9 square feet/yard^2 = 63 square feet.
To find the total area, we add up the areas of the individual fabric pieces:
36 square feet + 36 square feet + 63 square feet = 135 square feet.
Therefore, the total area of fabric needed for the quilt is 135 square feet.
