Step-by-step explanation:</h3>
In order for three line segments to form a triangle with non-zero area, they must satisfy the "triangle inequality." There are several ways to express this, but perhaps the simplest is ...
a + b > c
where a, b, and c are the lengths of sides in order from shortest to longest.
Here, that means the requirement for a triangle is ...
4 + 4 > 7 . . . . true, so <em>a triangle can be formed</em>
The triangle inequality is satisfied by these segment lengths.

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
