Answer:

Explanation:
To find the area of the baseboard, we need to multiply the length by the width:
- The length of the baseboard is given as 15 metres.
- The width of the baseboard is given as
metre.
To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):
Now we can multiply the length and width:
Therefore, the area of the baseboard is 13.5 m².
