Question

The sides of a triangle are in the ratio 5 :8 :12.if the perimeter of the triangle is 288cm, find the
Longest side
Shortest side

Answer 1

Answer: Longest side=109.44cm which is ratio 12 and the shortest side=45.6cm which is ratio 5

Step-by-step explanation: 5:8:12 add them together=25

5/25=5/25x228=45.6cm because 5x228/25=45.6cm

8/25=8/25x228=72.96cm because 8x228/25=72.96cm

12/25=12/25x228=109.44cm because 12x228/25=109.44cm

Therefore longest side=109.44cm which is ratio 12 and the shortest side=45.6cm which is ratio 5
