Best Answer

You can't tell the dimensions from knowing only the area. There are an infinite number

of rectangles that all have different dimensions but all have areas of 30 square feet.

Here are a few of them:

Length x Width

30' x 1'

15' x 2'

10' x 3'

7.5' x 4'

6' x 5'

Q: If a rectangle had an area of 30 square feet what are the measurements of its length and width?

You an calculate the area of a rectangle by multiplying length x width.

you need length and width length multiply width = area length + length + width + width = perimeter

For a rectangle or square, Area = Length * Width So Length = Area / Width.

The area of a rectangle is simply length x width. If the measurements are in centimeters, then the area will come out in square centimeters.

The area of a square or rectangle can be found by multiplying the length times the width. In a square both the length and width are the same measure.

You need two measurements for a rectangle: length x width. If both are equal, you should say so (in this case, it is a square).

For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 270 square feet.
