Explanation:
Given the information:
- 1st square: 12 square units
- 2nd square: DOUBLE that of the first square = 2*12 = 24 square units
From that, we can determine the length of the side in each square:
1/
![x^(2) = 12](https://img.qammunity.org/2021/formulas/mathematics/high-school/2ci8q7nxa5ksw412k249jahgoz9pdf0b0k.png)
<=> x = 2
2/
![a^(2) = 24](https://img.qammunity.org/2021/formulas/mathematics/high-school/yqa72jh22uo6t45hiemyuzxmq3yjg0170g.png)
<=> a = 2
