1.82 + 2.42 + 1.52 - 1.8 X 2.4 - 2.4 X 1.5 - 1.8 X 1.5 a2 + b2 + c2 - ab - bc - ac = (1/2) X [(a - b) 2 + (b - c) 2 + (c - a) 2] So, 1.82 + 2.42 + 1.52 - 1.8 X 2.4 - 2.4 X 1.5 - 1.8 X 1.5 = (1/2) X [(1.8 - 2.4) 2 + (2.4 - 1.5) 2 + (1.5 - 1.8) 2] = (1/2) X (0.36 + 0.81 + 0.09) = (1/2) X (1.26) = 0.63
