To find the height of the poster, we can use the formula for the area of a rectangle:
Area = Length × Width
Given that the area is 30 square inches and the width is 5 inches, we can substitute these values into the formula:
30 = Length × 5
To isolate the unknown variable (Length), we need to solve for it. We can do this by dividing both sides of the equation by 5:
30 ÷ 5 = Length
This gives us:
6 = Length
Therefore, the height of the poster is 6 inches.
