Step-by-step explanation:

${(14 \sqrt{6}) }^{2} = 2 {a}^{2} \\ {14}^{2} \times { \sqrt{6} }^{2} = 2 {a}^{2} \\ 196 \times 6 = 2 {a}^{2} \\ 1176 = 2 {a}^{2} \\ {a}^{2} = 588 \\ a = \sqrt{588} = \sqrt{196 \times 3 } \\ = 14 \sqrt{3} \\ a = b = 14 \sqrt{3}$

Roger will benefit

Step-by-step explanation:

38 times 4 = 152 without membership for Grace

38 times 6 = 228 without membership for Roger

20 times 4 = 80 + 80 = 160 (Grace cost with membership)

20 times 6 = 120 + 80 = 200 (Roger cost with membership)

152 - 160 = -8 ( Grace pays $8 more with the membership)

228 - 200 = 28 ( Roger saves $28 with a membership)

So Roger gets the better deal.
