4. C (Third choice from top)
Answer:
sqrt(area)
Explanation:
- Here sqrt is a short form of square root.
- area is a variable name having he area of square.
- When the function is called, it will give the square root of the value stored in variable area.
As we have to find the length of the diagonal, we must knew that as all sides of the square are same in length so are the diagonals. This means that each of the four sides of the square and it diagonals are equal in length.
So a square has: length=breadth=diagonal
As Area= length*breadth
√area = length (as length = diagonal length)
So √area = diagonal length

multiplication and division operators and other values in a spread sheet is
known as formulas. They are a way of having to provide symbols in means of
expressing information regarding a mathematical formula that are being solved
or showing its solution along with it.
