To find the area of a square, square the length of one side. For example, if the side length is 4 inches, the area is 4² = 16 square inches (in²).
To find the area of a square with a side length of s inches, you need to use the formula for the area of a square, which is Area = s², where 's' represents the length of a side of the square.
Let's consider an example. If each side of the square is 4 inches, to find the area, you would square the side length. In this case, that would be 4² = 16. Therefore, the area of this square is 16 square inches.
The symbol for square inches is in², reflecting that we are measuring area or a two-dimensional space. This concept can be extended to any unit of measurement; if we were using feet instead of inches, for example, we would express the area in square feet (ft²).

Answer:
Formula for nth term in Arithmetic sequences is:
where a is the first term, d is the common difference and n is the number of terms.
As per the statement:
The rule for the pattern is add 4.
As the first term in line says the first term i,e 7
common difference(d)= 7
As the Jenna number is 8th in line.
Series we get;
7, 11, .........
We have to find the 8th term.
n = 8, a = 7 and d = 4
Using above formula:
Therefore, 35 number should Jenna say.
