Answer:
22cm , 33cm , 44cm❓❓
Step-by-step explanation:
Ratio of three sides of triangle = 2:3:4
Let the three sides be 2x, 3x and 4x
Perimeter of triangle = 99cm
sum of 3 sides = 99cm
2x + 3x + 4x = 99cm
9x = 99cm
x = 99/9
11cm
Thus, the length of three sides are 2*11 = 22cm, 3*11 = 33cm & 411 44 cm
