Question

If area of a square plate is 100 m², then what is the side length of the square plate and its perimeter respectively?

Answer 1

Area of a square = ${\text{side}}^2$
Area of square$=100m^2=(10m{)}^2$
$\therefore$ The side length is 10 m.
Perimeter of a square = 4 $\times$ side
$⟹$ Perimeter = 4 $\times$ 10 = 40 m
