To express the length in terms of centimeters, we first need to convert the millimeters to centimeters, as 1 centimeter is equal to 10 millimeters.
Given that Zebiba measured the length as 54 cm and 4 mm, we can convert the 4 mm to centimeters.
First, let's convert 4 mm to cm:
4 mm = 4/10 cm = 0.4 cm
Now, adding the original length measured in centimeters to the converted length:
54 cm + 0.4 cm = 54.4 cm
So the length of the table is 54.4 cm. If you'd like to express this in its most reduced form, it's already in its lowest form.
