Answer:
30 cm, 35 cm and 50 cm
Step-by-step explanation:
Sum the parts of the ratio, 6 + 7 + 10 = 23 parts
Divide the perimeter by 23 to find the value of one part of the ratio.
115 cm ÷ 23 = 5 cm ← value of 1 part of the ratio
Thus the lengths of the sides are
6 × 5 cm = 30 cm
7 × 5 cm = 35 cm
10 × 5 cm = 50 cm
(30 + 35 + 50 = 115 )
