    Step-by-step explanation:

    ▪️Perimeter of rectangular hall = 2(l + b) = 250 m

    ▪️Total cost of painting = Rs.15000

    ▪️Rate per m2 = Rs.10

    ▪️Area of four walls = 2(l + b) h m2 = (250×h) m2

    Area of four walls = 2(l + b) h m2 = (250×h) m2A/q,

    ▪️(250×h)×10 = Rs.15000

    ▪️⇒ 2500×h = Rs.15000 

    ▪️⇒ h = 15000/2500 m

    ▪️⇒ h = 6 m 

    ▪️Thus the height of the hall is 6 m.
