If you double the side lengths of a rectangle why is the area of the new rectangle not twice as big as the original?

Look at it this way, suppose x is one side of the rectangle and y is the other. Then the area of the rectangle would be xy. Now if you double each side of the originial rectangle you would have each side as 2x and 2y. So the area of the new rectangle would be 2x*2y or 4xy. As you can see the new area is 4 times larger than the original.

How does doubling the side lengths of a rectangle affect its perimeter?
Both the side lengths and the perimeter are linear measurements, therefore they are proportional. In other words, twice the side length results in twice the perimeter.
If the area of a rectangle is 18 square inches and the length of the rectangle is twice it's width what is the length and width of the rectangle?
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
The length of a rectangle is 2in more than twice its width and the perimeter of the rectangle is 16in find the width of the rectangle?
Using algebra to solve this geometric problem, call the width w inches long.Therefore the length is 2w+2 inches (i.e. "2in more than twice its width").There are two widths and two lengths in the perimeter so now add them up. w+w+2w+2+2w+2=6w+4 The perimeter is equal to 16 inches, so 6w+4=16 6w=12 w=2 inches
The perimeter of a rectangle is 50 meters and its length is 12 meters. What is the width of the rectangle?
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
We are interested in the dimensions of a certain rectangle. This rectangle has length twice the side of the square and width three units less than its sides of this square. If the two areas are equal?
The rectangle is 12 units by 3 units.

The length of a rectangle is twice its width If the perimeter of the rectangle is 54y find its area?
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
Why does the area of a rectangle change?
if you change the side length the area will change. It is possible to change them and not change the area. For example make side twice and long and the other half as long. But in general, if you change the lengths of the sides the area of the rectangle changes.
How do their areas compare when one rectangle is twice as long as the other?
Area of a rectangle is Base(B) times Height(H).Area of smaller rectangle is BH.Area of larger rectangle is 2BH.Area of larger rectangle is twice as large as the smaller rectangle.
The length of a rectangle is twice the width width the perimeter is 48 in find the dimensions of the rectangle?
If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.

The perimeter of a rectangle is 130m The length is 2m more than twice the width What are the lengths and widths of the rectangle?
P = 130, so L + W = 65. 65 - 2 = 63, 63/3 = 21 m which is the width, making the length 21 + 21 + 2 ie 44 m

What does a double o g stand for?
OG means "original gangster" and a "double OG" is twice as original. A friend of mine wears zoot suits everywhere, and people exclaim "double OG" when they see him. I thought it meant "Old Guy" until I was corrected.
