Hi there !!
length of 1 side = a
Area = a² = 441 cm²
a = √441 = 21 cm
hence ,
the length of 1 side is 21 cm
length of 1 side = a
Area = a² = 441 cm²
a = √441 = 21 cm
hence ,
the length of 1 side is 21 cm

the area of square=S*S
441 =S²
√441=21 =side
then,
perimeter of square=4*side
4*21=84
so length of square =21
441 =S²
√441=21 =side
then,
perimeter of square=4*side
4*21=84
so length of square =21
