To find the length of a rectangle when you know the area, you also need to know the width, because the formula for the area of a rectangle is:
Area = Length × Width
In this case, we know the area is 500 square centimeters. So, we can rearrange the formula to find the length:
Length = Area / Width
Without the width, we can’t determine a specific length. For instance, if the width is 10 cm, the length would be:
Length = 500 cm² / 10 cm = 50 cm
Alternatively, with a width of 25 cm, the length would be:
Length = 500 cm² / 25 cm = 20 cm
Thus, you need to know the width of the rectangle to calculate the length accurately.
