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:
The answer is A.
Step-by-step explanation:
The angles add up to be 180°, which makes a supplementary relationship.
Hi Robles928518,
0,1x + 9 ≤ 45
0,1x ≤ 45 - 9
0,1x ≤ 36
x ≤ 360
x ∈ ] - ∞ ; 360 ]
So what I think you do is that yu have to simplify or divide. Good luck! - from: a 7th grader
