Final answer:
To find the area of the white part of the quilt, subtract the area of the purple square from the area of the white square.
Step-by-step explanation:
To find the area of the white part of the quilt, we need to subtract the area of the purple square from the area of the white square. The side length of the white square is 60 inches, so its area is 60 inches multiplied by 60 inches. The area of the purple square is given by the formula (x-5) inches multiplied by (x-5) inches. To find the area of the white part, we subtract the area of the purple square from the area of the white square.
Area of white part = Area of white square - Area of purple square
Area of white part = (60 inches) x (60 inches) - (x-5 inches) x (x-5 inches)
