Math Grade 7 Algebra

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

98x^2 +105x -27 when x = 5

= 98(5^2) + 105(5) - 27 = 2,948 = Area

2948 = LW

lenght & width could be any of an infinite number of dimensions

2948 = 2(1474) = 4(737) = 11 x67 x 2 x 2 in prime numbers

if the dimensions are integer numbers then they're some product of 2, 2, 11, and 67

such as

2 x 1474 = 2948 m^2

4m x 737m = 2948 m^2

44m x 67m = 2948 m^2

11m x 268m = 2948 m^2

or

1 x 2948 m^2

dimensions would then be one of the 5 above

there must be more information to the problem to narrow the answer down more?

also the question seems very strange for 7th grade. The instructor seems to be wasting a lot of students' time if f this is for real.

But it could be endless number of other lengths and widths, if the problem doesn't require integer dimensions
