Answer:
The correct answer is 1,44 meters long.
Step-by-step explanation:
Let's try to imagine the situation.
Seth is placing the boards next to each other, end to end.
Each board measures 0.24 meter long, but if he has 6 boards and places them in this way they will measure 6 times their size, that is, 0.24 * 6.
Therefore we should only solve that multiplication: 0.24 * 6 = 1.44.
In this way we can verify that the total lenght of the boards is 1.44 meters long.
