A company sells tents in two styles, shown below. The sides and floor of each tent are made of nylon. Which tent requires less n
BartSMP [9]

Answer:  Tunnel tent.

Step-by-step explanation:

The tent which has the minimum area requires less nylon to manufacture,

Since, the area of Pup tent = Area of 3 square each having side 8 ft + Area of 2 equilateral triangle having side 8 ft

= 3 \times ( 8^2 ) + 2\times \frac{64\sqrt{ 3} }{4}

=  192+ 2\times \frac{64\sqrt{ 3} }{4}

= 192+ 32\sqrt{ 3}

= 247.425625842\approx 247.43\text { square ft}

Now, the area of tunnel tent = Area of square having side 8 ft + total Area of half cylinder having radius 4 ft and height 8 ft

= 8^2 + \frac{1}{2} [ 2\pi\times 4(4+8)]

= 64 + \pi\times 48

= 64 + 3.14\times 48

= 214.72\text { square ft}

Since, 214.72 < 247.43

Thus, Tunnel tent requires less nylon to manufacture.

This is correct? I need help please :(
Leto [7]

Answer:

well, we only no that

2l + 2w is 80

(lengths and widths on all 4 sides

and that w * l is A

so the function should be w times what's left for l, but also expressed by something with w

2l + 2w = 80 | -2w

2l = 80 -2w | devide by 2

l = 80 - w

now we can substitute l in

A = w * l

so that we only need w's

A(w) = w * (80-w)

for any w it will give us the area, makes only sense for 0<w<80
