4.2.
If the 2 inch side was scaled to 10.5 inches the 5 inch side would be scaled by 10.5/2 = 5.25, so would be 25.125 inches which is too big.
So the 10.5 inches is the 5 inch side on the original, and so it 10.5/5 = 2.1 times bigger.
Therefore the smaller side would be 2*2.1/= 4.2 inches.
Base= x
Height= 4+x
Area = (1/2)(x)(4+x) = 6
Hence, quadratic equation is,
(x)(8+2x) = 12
