Answer:
40000
Step-by-step explanation:
length = 50m
width = 40m
the height = 10m
Area of ceiling = 50*40 = 200
Area of four walls = 2 ( 50*10 ) + 2 (40*10) = 1800
Total cost = (200+1800)*20 = 40000

length =50
breadth= 40
height = 10
Area of celling = l×b
= 2000 m square.
cost of celling = 20 × 2000
Hence answer is 40000
