Carson and Emily make a post for school. The poster is in the shape of a rectangle. The length of the poster measures seven units and the area of the poster is 42 square units. What is the width of the poster
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 is 7 units and the area is 42 square units, we can set up the following equation:
7 * width = 42
Solving for the width, we divide both sides by 7:
width = 42 / 7
width = 6
Therefore, the width of the poster is 6 units.
