Answer: 544 cm²
<u>Step-by-step explanation:</u>
There are 5 sections to the tent:
- Front (triangle): A =
· b · h - Back (triangle): same dimensions as Front
- Base (rectangle): A = L · w
- Left Side (Rectangle): A = L · w
- Right side (rectangle): same dimensions as Left Side
Total Surface Area = Front & Back + Base + Sides
= 2[
(12 · 8)] + (12 · 14) + 2(14 · 10)
= 96 + 168 + 280
= 544
