Answer 1

9 m

Explanation:

given,

area of floor of play pen = 5 m²

we know, area of a square = (side)² sq units

now according to the question,

5 = (side)²

⇒√(side)² = √5 [taking square root on both sides]

⇒ side = √5 m

now, we know,

perimeter of a square = 4 × side = 4 × √5 = 8.94 m (app.) ≈ 9 m
