I think the answer is 1/2. C.
Just plug in -1 for x and u should get ur answer
5 x 100,000,000 = 5,000,000,000
8 x 100,000 = 800,000
5,000,000,000 / 800,000 = 6250
Square root of 324 = 18 inches.
Perimeter = 18 inches x 4 = 72 inches.
18 times 4 because each side of square tile equals to 18 inches and there's 4 sides.
The answer is 72 inches.
Hope this helps.
