Respuesta :

Answer: 90cm, 180cm, 240cm

Explanation:

The extented ratio are 3 : 6 : 8.

Let the sides be denoted as 3x, 6x and 8x.

Perimeter = 510cm

3x + 6x + 8x = 510

17x = 510

Divide by 17 to get the value of x

x = 510/17

x = 30

The sides can be found as follows:

3x = 3 × 30 = 90

6x = 6 × 30 = 180

8x = 8 × 30 = 240

The lengths are 90cm, 180cm and 240cm.
