Question

if area of a square is 16 square meters,what will be its parameter

Answer 1

area of square = side × side
=16 square meter
side = 4 m

perimeter = 4× side
=4×4
=16m

Answer 2

since area of square=a^2
where a is side of square
a^2=16
a=
$\sqrt{16} = 4$

hence a=4
now perimeter= 4×a
perimeter of square=4×4=16meter
