Answer 2

Answer:

108 m²

Step-by-step explanation:

Let the breadth of each wall be 'x', then the length should be '3x'.

Area of 4 walls = 2(length + breadth)*height

⇒ 144 = 2(3x + x)*3

⇒ 144 = 6(4x)

⇒ 144 = 24x

⇒ 144/24 = x

⇒ 6 = x

Area of the floor = length x breadth

                   = 3x * x

                   = 3x²

                   = 3(6)² = 108 m²
