Answer:
90 cm, 180 cm, 240 cm
Step-by-step explanation:
Let the lengths of sides of the triangle be 3x, 6x and 8x

Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.
4.76 rounded to one decimal place is 4.8
Look at the decimal place you want to round (the 7, since it is the one decimal place).
Then look at the next digit (the 6). If it is 5 or greater, round up. Otherwise, round down.
You round up the 7 up because 6 is 5 or greater.
So you get the answer 4.8
