Answer:
perimeter = 85.6 cm (nearest tenth)
Step-by-step explanation:
Area of a square = [tex]x^2[/tex], where [tex]x[/tex] is the length of one side
Given area = 457.90 m²²
⇒ 457.90 = [tex]x^2[/tex]
⇒ [tex]x=\sqrt{457.9}[/tex]
⇒ [tex]x=21.4 \ \textsf{cm (nearest tenth)}[/tex]
Perimeter of a square = [tex]4x[/tex], where [tex]x[/tex] is the length of one side
⇒ perimeter = [tex]4 \times \sqrt{457.9}[/tex]
⇒ perimeter = 85.6 cm (nearest tenth)
