The perimeter of a triangle is 24 cm and the lengths of the sides
are in the ratio 3:4:5. Find the lengths of the three sides.

6, 8 and 10 cm

Step-by-step explanation:

Sum the [arts of the ratio, 3 + 4 + 5 = 12 parts

Divide the perimeter by 12 to find the value of one part of the ratio.

24 ÷ 12 = 2 cm ← value of 1 part of the ratio, thus

3 parts = 3 × 2 = 6 cm

4 parts = 4 × 2 = 8 cm

5 parts = 5 × 2 = 10 cm
