Answer:
41.13 sq m
Step-by-step explanation:
area of square = 4² = 16
there are two quarter-circles which equals one semicircle
area of semi-circle is πr²/2
A = 4²π/2 = 8π = 25.13
add together: 16 + 25.13 = 41.13
Rationalize both the numerator and denominator. Given

we can rationalize it by introducing conjugates of the numerator and denominator:

Then the limit is equivalent to

For the remaining expression, divide through uniformly by
:

As <em>n</em> goes to infinity, the remaining terms containing <em>n</em> converge to 0, leaving

making the overall limit 3.
