Question

calculate the area of the square whose perimeter is 36 CM​

Answer 1

Answer:

81 cm²

Step-by-step explanation:

The perimeter of the square is 36 cm.

Let the side of the square be x.

So, 4s = Perimeter

=> 4s = 36

=> s = 9 cm.

Area of square = s²

= 9²

= 81 cm².

Hence the area of the square is 81 cm².

Answer 2

As per the details provided in the question.

In the above question, we have the details as follow.

The given data is perimeter is 36cm.

We have to find the area of the square.

Here we have to use the formula of perimeter $P=4a$, area of a square is $A=a^{2}$

Thus, calculating the side of a square we get as follow,

$P=4a\\a=\frac{P}{4} \\a=\frac{36}{4}\\a=9cm$

Therefore the area of a square is,

$A=a^{2} \\A=9^{2} \\A=81sqcm$

Hence the area of a square is 81sqcm.
