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?

Answer 1

To find the width of the poster, we first need to find the formula for the area of a rectangle, which is:

Area = Length x Width

Given that the length is 7 units and the area is 42 square units, we can plug these values into the formula:

42 = 7 x Width

Now we can solve for the width by dividing both sides by 7:

Width = 42 / 7
Width = 6

Therefore, the width of the poster is 6 units.
