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?

Answer 1

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.
