Answer:
AC = 13.9 cm.
Step-by-step explanation:
See the attached diagram.
Draw a perpendicular on AD from B which is BE.
Now, CD = BE
Now, Δ ABE is a right triangle and
AB² = BE² + AE² {Applying Pythagoras Theorem}
⇒ 11² = BE² + (AD - DE)²
⇒ 11² = BE² + (11 - 4)² {Since CB = DE = 4 cm}
⇒ 11² = BE² + 7²
⇒ BE² = 11² - 7² = 72
⇒ CD² = 72
Now, Δ ACD is a right triangle and
AC² = CD² + DA² {Applying Pythagoras Theorem}
⇒ AC² = 72 + 11² = 193
⇒ AC = 13.89 ≈ 13.9 cm

Square is a quadrilateral with all sides being equal. The remaining area of the square can be represented as 64-16π.
<h3>What is the area of the square?</h3>
The area of a square is the product of the length of the square and the width of the square, but since all the sides of the square are equal the area of the square is the square of any of its sides.
We know that the four circles are arranged in the square as shown, below, therefore, four times the radius of a circle is the side of the circle. Also, the remaining area of the square is the difference in the area of the square and the area of the four circles, thus, we can write the remaining area of the square,
We know that the side of the square is 8 in, while the radius of the 4 circles is 2 in,
Hence, the remaining area of the square can be represented as 64-16π.
