Answer:
9.8x + 1.1y + 9.9z
Step-by-step explanation:


⇒ 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y
⇒ 9.8x + 1.1y + 9.9z
Answer: C) 9.8x + 1.1y + 9.9z
Step-by-Step Explanation:
Perimeter = Side + Side + Side
Therefore,
= 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y
= (5.5 + 4.3)x + (6.2 - 5.1)y + (8.3 + 1.6)z
= 9.8x + (6.2 - 5.1)y + (8.3 + 1.6)z
= 9.8x + 1.1y + (8.3 + 1.6)z
=> 9.8x + 1.1y + 9.9z
Perimeter = 9.8x + 1.1y + 9.9z cm
