Answer:
The room is in rectangular form with breadth 15 m and length 20m.
Step-by-step explanation:
Area of rectangle= l×b
since 2 metres of margin is left all around
new length = 20-2=18 m
new breadth= 15 - 2= 13m
Hence area = l× b
= 18 × 13 = 234 m
Cost of 1 m carpet = 800 rupees
cost of 234m = 800×234= 187200 rupees
