Question

Help me plz I don't know the choices it could be

Answer 1

Answer: 544 cm²

Explanation:

There are 5 sections to the tent:

1. Front (triangle): A =
   `(1)/(2)` · b · h
2. Back (triangle): same dimensions as Front
3. Base (rectangle): A = L · w
4. Left Side (Rectangle): A = L · w
5. Right side (rectangle): same dimensions as Left Side

Total Surface Area = Front & Back + Base + Sides

= 2[
`(1)/(2)`(12 · 8)] + (12 · 14) + 2(14 · 10)

= 96 + 168 + 280

= 544
