length*width = 2*width*width i.e square the width and multiply by 2
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
First find the dimensions of the rectangle. Let its length be 2x and its width be x: 2(2x+x) = 60 4x+2x = 60 6x = 60 x = 10 Therefore: length = 20cm and the width = 10cm Area = length*width Area = 200cm2
98 square feet
divide area by width and voila! u get the length
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
If Length * Width = Area, then Area ÷ width = Length
Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length)
For a rectangle, area equals length times width. To find the length given the width and area, divide the area by the width.
To find the relationship in width and area you can use the formula area/length = width. To find the area of a room you multiple the length by the width.

AREA = LENGTH x WIDTH LENGTH = 2 X WIDTH AREA = 2 x WIDTH X WIDTH = 900 900/2 = WIDTH X WIDTH 450 = WIDTH X WIDTH = WIDTH SQUARED WIDTH = SQUARE ROOT (450) = 21.21 FEET LENGTH = 42.42 FEET
Width * Length = Area so..... Width = Area / Length
You just multipy the length (no matter what it is) by the width (no matter what that is). So... L x W = A Where L is Length, W is Width and A is Area. For your question about the area of a rectangle where the length is twice the width but no numbers are given then I guess a formula could be W x 2W = A. Or send me the exact question and I'll see if I can think of a better answer.
Find the width, and multiply the length and the width.
For a rectangle or square, Area = Length * Width So Length = Area / Width.
