C) 60 meters
D) 72 meters
Plz, show an explanation!

Answer 1

Answer:

Option(B)

Step-by-step explanation:

Area of Square room = 144 m²

Then,

Area of square = s²

⇒ 144 = s²

⇒ s = √144

⇒ s = 12 cm

Thus, Side of square = 12 cm

Then,

Perimeter = 4 * side

                = 4 * 12

               = 48 cm

Therefore,

48 m of baseboard is needed.

Hope it helps!
