Answer:
B
Step-by-step explanation:
The common factor of the expression is 5x
The answer would be 
or 27.7 km² if rounded to the nearest tenth
Fractions can be defined as the representation of a part of a whole. A fractions consists of the numerator and the denominator.
let f(x) =
then 'p' represents the numerator; while 'q' represents the denominator;
where p and q belong to integers for simple fractions, while when p and q belong to other sets they can from complex fractions.
To convert a fraction into an integer we need to multiply the fraction with the the denominator so that it cancels out leaving only the numerator behind.
For fractions present in equations to get rid of all the fractions we new to multiply the equation by the LCM of the denominator of all the fractions.
Where LCM is the least common multiple.
To give an example:
let y = X +
Then the LCM for 4 and 5 will be 20;
as factor of 4 are 1,2 and that of 5 are 1,5
then to eliminate the fractions from the equation
Multiplying both sides by 20
y x 20= X x 20 +
x 20
20y= 3 x 5X + 9 x 4
20y = 15X + 36
