U just need to count how many numbers are in ur data.
There is one 1....so the one dot over the 1 is correct
There are four 2's....so the 4 dots over the 2 is correct
There is one 3....so 1 dot over 3 is correct
There are three 4's...but u only have 2 dots over the 4 when there should be 3....so ur answer is going to be 4 <==
The formula for the area of a square is:
A=s²
Since we known that the area is 81ft², we can solve for the length of a side.
A=s²
81=s²
find the square root of both sides
9ft=s
The length of each side is 9ft
You need to divide 6 on both sides and it will be 16
