Answer:
I think that the answer would be: 7 feet. I'm not sure though.
Step-by-step explanation:
The formula to finding the area is: length x width
And we already know two parts of that formula.
- the area: is 84 feet squared
- the width: is 12 feet
Now, all we have to find is the length/height. To do this, we can use the formula.
AREA=LENGTH/HEIGHT x WIDTH
Just substitute the information we have and........
84 = length x 12
-DIVIDE BY 12 ON BOTH SIDES-
7 = length
Done! Now you have your length as 7 feet. I hope this is correct and help you.
