Answer: 9 meters
To answer this question you need to know the formula to calculate the area of a square. Square has same side length so the area is: length x length.
Then the calculation would be:
Area= length x length
81m2= length x length
Length ^2= 81 m2
Lengtj= <span>√81 m2</span>
Length= 9 meters
Answer:
4 days
Step-by-step explanation:
If 8 machines can complete a task in 7 days, how long will 14 machines take?
So, it is obvious that if the number of machines increases, the number of days taken to complete the task decreases; thus proving that this is an indirect / inverse proportion.
Let's take <em>x</em> as the number of days we need to find out.
8 machines : 7 days
14 machines : <em>x</em> days
14 × <em>x </em>= 8 × 7
14<em>x </em>= 56
x = 
x = 4
