Answer:

35 cm, 45 cm, 50 cm

Step-by-step explanation:

Sum the parts of the ratio, 7 + 9 + 10 = 26 parts

Divide 130 cm by 26 to find the value of one part of the ratio

130 cm ÷ 26 = 5 cm ← value of 1 part of the ratio, thus

7 parts = 7 × 5 cm = 35 cm

9 parts = 9 × 5 cm = 45 cm

10 parts = 10 × 5 cm = 50 cm
