Answer:
the length of the sign is inches
Step-by-step explanation:
Given
Area of the square of design =
First we find the roots of equation
The roots of the quadratic equation are given by
where
That is, the factors of the polynomial are
and
.
So, Area of the square design = =
Area of a square = Length^2
Thus, the length of the sign is inches
