The width of Zorn's patio is labeled in the diagram below. If the perimeter of the patio is (30x + 26) feet, what is the length of the patio?

2x^2=450

Determine which statement is true about the solutions to the equation.

The solutions are -15 and 15 and both are reasonable side lengths.

The solutions are -30 and 30 and both are reasonable side lengths.

The solutions are -30 and 30 but only 30 is a reasonable side length.

The solutions are -15 and 15, but only 15 is a reasonable side length.

we have that
2x²=450 ----------> x²=450/2----------> x=√225
x1=+15
x2=-15

a reasonable length measurement should be positive
therefore

the answer is
The solutions are -15 and 15, but only 15 is a reasonable side length.
