1.	The sides of a triangle are in the ratio 1: 2: 3. If the perimeter is 36 cm, find its sides.
Answer» Given sides of a triangle are in the ratio 1: 2: 3 Perimeter = 36 cm Sum of the terms of the ratio = 1 + 2 + 3 = 6 First side = (1/6) × 36 = 6 cm Second side = (2/6) × 36 = 2 × 6 = 12 cm Third side = (3/6) × 36 = 6 × 3 = 18 cm

The sides of a triangle are in the ratio 1: 2: 3. If the perimeter is 36 cm, find its sides.

Answer»

Given sides of a triangle are in the ratio 1: 2: 3

Perimeter = 36 cm

Sum of the terms of the ratio = 1 + 2 + 3 = 6

First side = (1/6) × 36

= 6 cm

Second side = (2/6) × 36

= 2 × 6

= 12 cm

Third side = (3/6) × 36

= 6 × 3

= 18 cm
