Answer 2

$\huge \sf \fbox{Solution :}$

Given ,

Perimeter of square = 36 cm

We know that , the perimeter of square is given by

$\sf \large{ \fbox{Perimeter \: of \: square = 4 × Side }}$

Substitute the values , we get

$\sf \hookrightarrow 36 = 4 \times Side \\ \\ \sf \hookrightarrow Side = 9 \: cm$

Hence , the side of square is 9 cm

Now , the area of square is given by

# Area of square = (side)²

Substitute the value , we get

=> Area = (9)²

=> Area = 81 cm²

Hence , the area of square is 81 cm²
