How do you find the length of a rectangle given the area and width?
Length = Area + Width
Length = Area - Width
Length = Area / Width
Length = Area * Width
Объяснение
Area of a rectangle is length multiplied by width, so if the area and width are known, divide the area by the width to get the length.
