Answer:
Maximum area = 9 sq units
Step-by-step explanation:

which represents the area . As it is a quadratic equation it represents the parabola . And the vertex of the parabola will maximum area of for some value of x
let f(x) = y


Comparing it with the standard equation of parabola

we get h=3 and y=9
where (h,k) is the vertex (3,9)
Hence the maximum area of the rectangle will be 9
Remember that multiples are numbers that can be divided by a number without a remainder so in this case you could add 15 by 15 to find what number in this set is a multiple of 15.




Therefore your answer is "60."
Hope this helps.
