It depends on what information you do have.
The length and area, the length and diagonal, the length and perimeter, etc. Each set generates a different answer.
With that much information, the area is unknown.
the length of a rectangle is 8 more than the width. the area os 345 centimeters. find the length and width of the rectangle
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
Area of rectangle divided by its length = width of rectangle
Multiply the length and width to find the area of both a rectangle and square.
The area of a rectangle is always the product of its length and its width. Call the unknown width w. Then 59w = 1740.5; w = 29.5 feet to the maximum possible number of justified significant digits. (59 has only two.)
length times width
For a rectangle or square, Area = Length * Width So Length = Area / Width.
The width is 16 feet
In order to find the area of a rectangle, multiply the length by the width of the rectangle. For example: If the length of a rectangle is 5cm and the width of a rectangle is 2cm, then the area of the rectangle would be 5cm X 2cm = 10cm².
