The correct answer is 10cm, 18cm, 20cm.
To find the lengths of the sides of the triangle, we need to first multiply each of the extended ratios by a constant factor to get the actual lengths. The total parts in the ratio is 5+9+10 = 24, so the constant factor is 48 cm / 24 = 2 cm per part.
Therefore, the lengths of the sides are:
5 parts * 2 cm = 10 cm
9 parts * 2 cm = 18 cm
10 parts * 2 cm = 20 cm
So, the lengths of the sides of the triangle are 10 cm, 18 cm, and 20 cm.
The lengths of the sides of a triangle are in the extended ration 5:9:10. The perimeter of the triangle is 48 cm. What are the lengths of the sides?
10cm,18,cm,20cm
5cm,9cm,10cm
12cm,16cm,20cm
15cm,27cm,30cm
