Answer:
To find the area of the rectangular sides, use the formula A = lw
To find the area of the triangular faces, use the formula A = 1/2bh,
Step-by-step explanation:
1st formula where A = area, l = length, and h = height.
2nd formula where A = area, b = base, and h = height.
To find the surface area of the triangular prisms, you need to use the following formula: A=2AB(a+b+c)h.
To find AB you use this formula:AB= square root of (s(s﹣a)(s﹣b)(s﹣c))
Substitute your values and you will be able to find your surface area.

i just subtracted 58 from 33.
For the first city, the 95% confidence interval would be:
28,900 +/- 2300 x 3 = 28,900 +/-6900$
For the second city, the 95% confidence interval would be:
30,300 +/- 2100 x 3 = 30,300 +/- 6300$
