Carson and Emily make a poster for school. The poster is in the shape of a rectangle. The length of the poster measures 7 units, and the area of the poster is 42 square units. What is the width of the poster?(1 point)
To find the width of the poster, we can use the formula for the area of a rectangle, which is length times width.
Given that the length of the poster is 7 units and the area is 42 square units, we can set up the following equation:
7 * width = 42
Now, we can solve for the width:
width = 42 / 7
width = 6
Therefore, the width of the poster is 6 units.
