9 1/4 because -3 1/2 * -3 1/2 = 9 1/4

let's firstly convert the mixed fraction to improper fraction.


\bf \stackrel{mixed}{3(1)/(2)}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} \\\\[-0.35em] ~\dotfill\\\\ \left( -\cfrac{7}{2} \right)^2\implies \left( -\cfrac{7}{2} \right)\left( -\cfrac{7}{2} \right)\implies \left( \cfrac{7^2}{2^2} \right)\implies \cfrac{49}{4}\implies 12(1)/(4)
