Carson and Emily make a poster for school. The poster is in shape of a rectangle, The length of the poster measures 7 units , and the area of the poster is 42 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:
Area = length x width
Given that the length is 7 units and the area is 42 units, we can plug these values into the formula:
42 = 7 x width
Now, we can solve for the width:
width = 42 / 7
width = 6 units
Therefore, the width of the poster is 6 units.
