Answer:
<em>The answer is 24</em>
Step-by-step explanation:
The given triomino follows as sequence that,
<em>The upper no. × The right no. -The left no. = The middle no </em>
As we can see this by analyzing the three triominoes
first triominoes
4 × 2 - 4 =4
second triominoes
6×1 - 5 = 1
third triominoes
3×4 -0 = 12
∵ Finding fourth triominoes
9×3 - 3 = 24
<em> </em><em> ∴ The answer is 24</em>
