What is the answer for this question and tell me how to do it

Answer:
1,226 centimeters
Step-by-step explanation:
We can first find the length of Frankie's garden in meters:
[tex]15.24\text{ m} - 2.98\text{ m} = 12.26 \text{ m}[/tex]
Then, we can convert this to centimeters by multiplying it by the unit ratio:
[tex]\dfrac{100\text{ cm}}{1\text{ m}}[/tex]
↓↓↓
[tex]12.26\not\!\!\!\text{ m} \times \dfrac{100\text{ cm}}{1\not\!\!\!\text{ m}} = \boxed{1,\!226\text{ cm}}[/tex]
So, the length of Frankie's garden is 1,226 centimeters.
