Answer:
19. The perimeter of a triangle = 850
Let 1st side be = 6x
2nd side be = 7x
3rd side be = 4x
Perimeter of a triangle = Sum of all sides
850 = 6x+7x+4x
850 = 17x
850/17 = x
50 = x
1st side of a triangle = 6x = 6×50 = 300
2nd side of a triangle = 7x = 7×50 = 350
3rd side of a triangle = 4x = 4×50 = 200
Check :- 300 + 350 + 200 = 850
