Infinitely many.

Suppose the length of the rectangle if L feet where L is any number greater than sqrt(42) = approx 6.481 ft.

Let the width of the rectangle be W = 42/L feet.

Then its area is L*W = L*42/L = 42 sq ft

There are infinitely many possible values for L and so infinitely many rectangles.

If the area is 10 square feet what are the dimensions?

If I only know the area, I can't tell you the dimensions. It all depends on the shape. A circle and a square give two different answers, and there are millions of rectangles, with different dimensions, that are all perfectly good and completely correct answers.


What are three different rectangles that have an area of 12 square units?

Thee different rectangles with an area of 12 square units are 3 by 4, 2 by 6 and 1 by 12.


How many square feet in a rectangle 193X273X214x205?

Rectangles have two dimensions: length and width. Multiply them together and you will get the area in square units.


What is an example of two rectangles having the same area but different dimensions?

The area of a rectangle is equal to its length times its width. So any two rectangles for which these dimensions have the same product, the area is the same. For example, a rectangle that is two meters wide and three meters long and one that is one meter wide and six meters long will both have an area of six square meters.


What is the area of a rectangle with a length of 35m and a width of 35m?

Area = 35*35 = 1225 square m With the dimensions given it is not a rectangle but it is a square <><><><> Above is correct- but squares are also rectangles.

What are the dimension of 45 square feet?

You can't tell the dimensions from knowing only the area. There are an infinite number of different shapes, all with different dimensions, that all have the same area. Even if you restrict it to only rectangles, there are still an infinite number of rectangles with different dimensions that all have the same area. Here are a few examples: 1 x 45 2 x 22.5 3 x 15 3.75 x 12 4 x 11.25 5 x 9 5.625 x 8 6 x 7.5 10 x 4.5 All of these rectangles have the same area . . . it's 45.


Why do mathematicians chose to measure area in squares instead of in rectangles or triangles or circles?

Because they (IMO) have the simplest area to find, to just square side. Triangles are half of a square Rectangles are uneven. Circles are rounded, and hard to find the area of. Plus, a square has 2 equal dimensions, so think 2D.


How many rectangles are in a rectangle?

There are an infinite number of rectangles for any given area, while there is only one square for any given area. The number of integer-value rectangles depends on the area and the number of integer factors of a whole-number area. Example: a rectangular area of 6 square inches could be enclosed by rectangles that were 1x6, 2x3, 3x2, and 6x1. Non-integer dimensions would include 1.5x4 and 1.2x5 inches.


What width and length dimensions equal 387.5 square foot area?

You can't tell the linear dimensions if you only know the area. There are an infinite number of rectangles, with different dimensions, that all have the same area. Here are a few for 387.5 . . . 1 x 387.5 2.5 x 155 3.1 x 125 5 x 77.5 15.5 x 25 19.685 square These all have the same area. There are an infinite number of others.


What are the dimentions in 425 square acres?

There seems to be a misunderstanding. Acres are a unit of area, not a unit of length like dimensions. To find the dimensions of an area in acres, you would need additional information such as the shape of the area (rectangle, square, circle, etc.).


What are the dimensions of 91.4 square meters?

You can't tell the dimensions from the area. There are an infinite number of different shapesthat all have the same area. Even if you want to restrict it to a rectangle, there are stillan infinite number of rectangles with different dimensions that all have the same area.Here are just a few rectangles. All of these have areas of 91.4 square meters:1 x 91.4 meters2 x 45.72.5 x 36.564 x 22.855 x 18.288 x 11.42510 x 9.1416 x 5.7125
