Answer:
405 in²
Explanation:
Given that :
Total area of quilt = 540 in²
Number of Blue patches = 27
Number of white patches = x
Area per patch = 5 in²
Area of white = total area - total area of blue patch
Total area of blue patch = 27 * 5 in² = 135 in²
Area that is white :
540 in² - 135 in²
= 405in²
