Question

The park is a rectangle with an area of 98x^(2)+105x-27m^(2). Find the length and width of the park, if x=5 meters.

Answer 1

If x is in meters, the expression 98x^(2)+105x-27m^(2) has mixed unit of meters and meters squared. The units are inconsistent with an area. There appears to be something missing in the information if we strictly consider the units of x as meters. Maybe the diagonal of the rectangle be defined by 98x^(2)+105x-27m^(2)?

Be Well.
