Hint: Let us assume that the length of the given square is cm. Let this be equation (1). We very well know that if the length of the side of a square is equal to cm, then the area of the square is equal to sq.cm. Let us say that the area of the square is equal to sq.cm. So, we are now supposed to find the square of value of cm which is obtained from equation (1). Let this be equation (2). Now, from equation (2) we can easily find the value of the area of the square whose sides are cm long.
Complete step-by-step answer:
Before solving the given question, we should keep in mind that if the length of the side of a square is equal to cm, then the area of the square is equal to sq.cm.
It is already given that the length of the side of the square is equal to 6 cm. Let us assume that the side of the square is equal to .
---(1)
We already know that the area of the square with side cm is equal to sq.cm.
--(2)
Now, we substitute equation (1) in equation (2). After doing so, we get,
So, it is clear that the area of the square whose side is equal to cm is sq.cm.
Thus, Area = .
So, the correct answer is “Area = ”.
Note: There is usually a misconception among students, which is that if the diagonal of a square is equal to cm, then the area of the square is equal to sq.cm. Due to this misconception the answer gets affected. Thus, this misconception should be avoided.
