(2,-17) should be the minimum.
Step-by-step explanation:
The minimum of a quadratic function occurs at
. If a is positive, the minimum value of the function is 
occurs at 
Find the value of 
x = 2
evaluate f(2).
replace the variable x with 2 in the expression.

simplify the result.



The final answer is -17
Use the x and y values to find where the minimum occurs.

The room is not in shape of a square but a rectangle.
Question says Length is: 19 inches
Diagonal is: 20.6 inches
In a square all sides are equal
Rectangle has just two sides equal
1/4 squared would be 1/4 times 1/4 which would eqaul 0.063
