The answer to your question would be 360 cm squared :)
Answer:
16320
solution: 12 / 1/4 = 3.
4 divided by 1/4 = 20
4 1/4 divided by 1/4 = 17.
3 x 20 x 17 =
the answer is 16320.
According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in all the fraction then you get
<span>a²/bc+b²/ca+c²/ab=3.
