Final answer:
To find the width of the rectangle, divide the area by the length. With an area of 20 square inches and a length of 5 inches, the width is calculated to be 4 inches.
Step-by-step explanation:
To find the width of a rectangle when the area and length are known, we use the formula for the area of a rectangle: Area = Length × Width. Here, the area is given as 20 square inches and the length as 5 inches.
We can rearrange the formula to solve for the width:
Width = Area ÷ Length
Now, plug in the known values:
Width = 20 square inches ÷ 5 inches = 4 inches
Therefore, the width of the rectangle is 4 inches, which corresponds to Option 1. This calculation showcases how rearranging the area formula enables the direct calculation of the width when the area and length values are known
