Answer:
630 minutes.
Step-by-step explanation:
That would be the lowest common multiple of 10, 14 and 18
10 = 2 x 5
14= 2 x 7
18 = 2 x 3 x 3
The LCM = 2 x 3 x 3 x 5 x 7
= 630.
We need the length of the sides.
AB=√(2-(-2))²+(4-1)²=√16+9=√25=5; BC=√4²+0=4; CA=√0+9=3. AB+BC+CA=5+4+3=12.
We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA=

. Hence CM=GC+GM=3*

. Now, since GM is normal to AB, we have by the pythagoeran theorem that:

Hence, we calculate from this that AC^2= 28, hence AC=2*

=BC. Thus, the perimeter of the triangle is 2+4*
