Missing portion of the question:
Question has missing the images for both type of tents hence the lengths were also missing which is attached in the picture.
Answer:
Tunnel Tent requires less nylon as its area (214.80ft²) is less than the area of Pup tent (247.40ft²)
Explanation:
Pup Tent:
Area for Pup Tent: (Perimeter)(Height) + 2 (Area of front triangular side)
Perimeter=sum of all sides = 8+8+8=24
Height = 8
Area of Triangle = (1/2) length * height
length=8
height can be calculated by Pythagorean Theorem:
hyp²=base²+perp²
height = perp=4√3
So,
Area of Triangle = (1/2) length * height
=27.7
Hence,
Area for Pup Tent: (Perimeter)(Height) + 2 (Area of front triangular side)
=(24)(8)+(2)(27.7)
=247.40m²
Tunnel Tent:
Area of tunnel tent = πrh + πr² + 2rh
π=constant=3.14
r=radius=4
h=height=8
Area of tunnel tent = πrh + πr² + 2rh
=(3.14)(4)(8)+(3.14)(4)²+2(4)(8)
=214.80m²
