Explanation:
We can use the formula for the area of a rectangle, which is:
Area = length x width
In this case, we know that the area of the rectangle is 6 m² and the length is 4 m. So we can substitute these values into the formula and solve for the width:
6 m² = 4 m x width
Dividing both sides by 4 m, we get:
width = 6 m² / 4 m
Simplifying, we get:
width = 1.5 m
Therefore, the width of the piece of wood is 1.5 m.
