81
Step-by-step explanation:
We need to know the sides of the square so 36÷4=9
Area of a square = Side x side
Area of square = 9x9=81
81cm²
Formula for area of a square with given perimeter: [tex]A=\frac{1}{16}P^2[/tex]
We are given the perimeter of 36 cm.
[tex]A=\frac{1}{16}36^2\\\\ A=\frac{1}{16}1296\\\\A=81[/tex]
The area should be 81cm².
