Answer:
Rs. 1250
Step-by-step explanation:
area of one tile = b × h
= 45 × 15
= 625 sq cm
area of 400 tiles
= 625 × 400
= 250000 sq cm
10000 sq cm = 1 sq m
250000 sq cm = 250000/10000 = 25 sq m
cost of polishing @ 50 per meter
= 25 × 50
= 1250
total cost of polishing = Rs. 1250
hope you get your answer
