Answer 1

Answer:

area=81 m square

side = $\sqrt{81}$

side= 9m

perimeter= 4×side

perimeter=36 m

Answer 2

Area of square=81m^2

Area of square=side×side

Let the length of side of square be Xm

Side×Side=81

X×X=81

X^2=81

X=√81

X=9

length of side of square =9m

perimeter of square =4×side

perimeter=4×9m=36m
