That is the definition of the area of a rectangle. It does not work for any other shape.
You times length by width
area is................ length x width perimeter is .......... length x width x length x width * * * * * WRONG. Area is the amount of space occupied by a shape. In the case of a rectangle, it is length x width, as stated above. But that does not work for circles, ellipses, triangles, other quadrilaterals and polygons and many other shapes, all of which have areas. A perimeter is the sum of all the lengths bordering the shape. The perimeter of a rectangle is NOT length x width x length x width but their sum! But again, that does not work for most other shapes.
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.
The width of a rectangle is the length of the shorter side.
X * X * X = X3 All three dimensions are covered by finding volume and this is a cubic function.
You times length by width
The length and width of a square are equal. Thus, find the square root of the area and the answer = length= width.
length*width = 2*width*width i.e square the width and multiply by 2
Length x width
To work out the area of a rectangle, multiply the length and the width. Therefore: Area=23*20=460
If you pretend that the width is X .Then you'll know that X times length = area. So if you say the length is 5 ,then the area is 10 the X must be 2 so the width is 2you simply work out what times the length makes the area.
width times length multiplied.
If it is a quadrilateral, you take the length times the width.
this answer is simply division just for a reminder of what I am doing here are how to work these length times width = area area divided by width = length area divided by length = width. we will be doing the second equation so 132 divided by 6 = 22 answer is 22
2D-Height x Width 3D-Height x Width x Length

Its width is 11.5 cm.Knowing that, it will be easy for you to reproduce the work.
