Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40

40+89.6=129.6

the area of the bottom is 7*8=56

the total area is 129.6+56=185.6

I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice. 
I'd suggest 185.6, the total surface area.

mezya [45]

Answer:

16.6

Step-by-step explanation:

The rectangle has an area of 105. It's width is 7.

1: Find the length

     \frac{area}{width}=length

     \frac{105}{7}= 15

      Length=15

2: Pythagorean theorem

      a^{2} +b^2=c^2

       7^{2}+15^2=c^2

       49+225=c^2

        275=c^2

         \sqrt{275} = \sqrt{c^2\\}

          16.55≈c

           Rounded to nearest tenth

              16.6
