The <u>whole number</u> <u>closest </u>to √22 is 5.
The square root of 22 is:
= √22
= 4.69
The whole number that it is closest to will <u>depend on the first decimal point</u>. 
If it is 5 or above then it will be closest to 5.
If it is 4 and below, then it is closest to 4.
The first decimal point is 6 so √22 is closer to 5. 
In conclusion, the square root of 22 is closer to 5.

<span>Pythagorean triple
a^2 + b^2 = c^2
so
5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169

Answer:
E.200.5ft²
Step-by-step explanation:
To find the area of the composite figure we simply split it into two regular shapes, a half circle and a square, we then find the area of the two shapes individually and add them together. 
Area of square = s² where s = side length 
It appears the given side length is 12 so s = 12
Which means area = 12² = 144ft²
For semi circle 
Area = 1/2(πr² ), where r is the radius 
The side length of the square is shared with the diameter of the semi circle meaning that the diameter of the semi circle is 12
To convert to radius from diameter we simply divide by 2 so r = 12/2 = 6
We have area = 1/2(πr² ) and r = 6 
So area = 1/2(π6²) 
==> evaluate exponent 
Area = 1/2(36π)
==> take one half of 36
Area = 18π
==> multiply 18 and π 
Area = about 56.5
Finally we add the two areas together
Total area = 56.5 + 144 = 200.5ft²
