Help fast please Mario completely covered a square floor using 98.5 ft² of hardwood without any overlap. Which measurement is closest to the side length of this floor in feet?

9.5 ft

10 ft

25 ft

48ft

The answer is 10 ft. I took the test but it didn't explain why it was the answer.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
