Question

If the area of a square is 100 metre,then what is its perimeter

Answer 1

Area of the square = 100 m^2
Now, According to the formula,
Area of the square is = Side × Side
or, 100 m = Side^2
or, Side = root 100 m
or, Side = 10 m

Therefore,each side of the square is 10 m
Now, According to the formula,
Perimeter of the square = 4×side
= (4×10) m
= 40 m (ans)

Answer 2

the perimeter of square is 40 meter
