Answer:
Let the breadth of the room be (x)m. Then,
length = x + 50 % of x
= x + 50/100 × x
= x + x/2
= 2x + x/2
= 3x/2
Area of floor = 924/38.50
=> l × b = 924 × 100/3,850
=> x × 3x/2 = 24
=> 3x^2/2 = 24
=> x^2 = 24 × 2/3
=> x^2 = 16
=> x = √16
=> x = 4
Hence , breadth = 4m
length = 3 × 4/2
= 6m
Area of four walls = 1,320/5.50
=> 2(l+b) × h = 1,320 × 100/55)
=> 2(6+4) × h = 240
=> 10h = 240/2
=> 10h = 120
=> h = 120/10
=> h = 12m
Hence , the dimensions of the room is 6m , 4m and 12m.
