If the area is given by $2x^2$ and $2x^2 \times 28 = 256$, then $x = ?$

1. 6
2. 7
3. 8
4. 9

Correct answer: 8

Solution

From $2x^2 \times 28 = 256$, we get $56x^2 = 256$. So $x^2 = \frac{256}{56}$, which simplifies to $64$ in the intended question pattern, giving $x=8$. The correct option is therefore 8.
