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 with 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:
Length = 7 units
Area = 42 square units
Let the width of the poster be represented by w.
Area = Length x Width
42 = 7 x w
To find the width, divide both sides by 7:
w = 42 / 7
w = 6
Therefore, the width of the poster is 6 units.
