Answer: By using EDL(Euclid's Division Lemma), the answer we get is 14
so,
     42 = 28(1) + 14
     28 = 14(2) + 0
therefore, HCF(or greatest common factor) = 14

Since it's a wall, I'm guessing it will only have access to half the circle? Therefore:
<em>Circle area formula: </em>πr²
<em>Radius:</em> 12/2 = 6ft
<em>Our case:</em> 
(π * 6²)/2 =
36π/2 =
18π = 56.55ft²
