Answer:
688 cm²
Explanation:
Area of triangular prism = Base × Height + Length × (perimeter of base)
Here given:
- Perimeter of Base: (6 + 12.4 + 12.4) = 30.8 cm
============================================
Surface Area = 6 × 12 + 20 × (30.8) = 688 cm²

Answer:
First, we need to calculate for x. Since,
MP = PN
Thus,
3x-4 = x+4
2x = 8
x = 4
Next, we calculate for MS
MS = 2x + 2 = 10
Since, MS = 2SQ
10 = 2SQ
Then,
SQ = 5 units
Therefore, the correct answer is B.
Hope this helps. Let me know if you have more questions.
X + 12 = n
N is 5 more than twelve so add 5 to 12 and you get 17.
