Given the area, there is no justification for assuming that it refers to a rectangular area: it could be circular, triangular or an even irregular shape.
However, if you make the totally unjustified assumption that it is a rectangle, then
8x^2 + 2x - 3 = (4x + 3)*(2x - 1)Therefore the two lengths are 4x + 3 and 2x - 1.
Conventionally, the length is the larger of the two sides and so, for positive solutions, the length is 4x + 3 units while the width is 2x - 1 units.

How do you find perimeterwhen the length and area is given?
take area and divide by length. this will give you width. take 2times width plus 2 times length and that is the perimeter
How do you find the area and perimeter of a rectangle?
Perimeter: Add the length of the four sides. Area: Multiply length x width.
Does width plus length equal the area of a room?
no length multiply by width
Formula for surface area of a pyramid?
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
How do you find a area and perimeter of a room in square meters?
Measure it with a meter stick. Multiply the length times the width to find the area. Two times the length plus two times the width is the perimeter.
Do you times the length and width or plus it?
to find the area of a rectange you times, to find the perimeter, you add them then times by 2

How do you find volume of a square?
Length plus height plus width.
What is the permeter and area ofthe shaded rectangle?
The area is the length times the width. The perimeter is two times the length plus two times the width.
What is the width of a rectangle with lenght 14cm and area 161cm?
To find the answer you would do 161 divided by 14 because width plus length equals area. You just do the problem backwards. the answer ends up being width=11.5cm
