The answer is 42, 289/4=72.25, then 121/4=30.25
so we subtract the answers, 72.25-20.25= 42
answer=42

Area of a square quilt = 289 square inches
Area of a smaller square quilt = 121 square inches

Area of a square = a²

Side length of big square quilt = √289 in² = 17 inches
side length of small square quilt = √121 in² = 11 inches

Perimeter of big square = 17 inches * 4 = 68 inches
perimeter of small square = 11 inches * 4 = 44 inches

difference = 68 inches - 44 inches = 24 inches.

If the area of a square is 25/36 the side length would be ____?
Zielflug [23.3K]
<h3>Answer:  5/6</h3>

Apply the square root to 25/36, which is the same as square rooting each piece of the fraction

sqrt(25) = 5

sqrt(36) = 6

Put another way, you can think of it in reverse:

(5/6)^2 = (5/6)*(5/6) = (5*5)/(6*6) = (5^2)/(6^2) = 25/36
