Question

the sides of a triangle are in the ratio 6:8:10. the perimeter is 120 cm. find the length of the shortest side.

Answer 1

the shortest side is 30. the sides are 30,40,50.

multiply each side in the ratio by 5 to get 30, 40, 50.

Answer 2

Length of the shortest side is:

30 cm

Explanation:

The sides of a triangle are in the ratio 6:8:10.

Let sides be 6x,8x and 10x

Perimeter=120 cm

⇒ 6x+8x+10x=120

⇒ 24x=120

⇒ x=5

Hence, sides are:

6×5=30 cm

8×5=40 cm

and 10×5=50 cm

Hence, length of the shortest side is:

30 cm
