Answer:  $25,500

<u>Step-by-step explanation:</u>

The given sequence {1300, 1300+150, ... } provides the following information:

  • the first term (a₁) = 1300
  • the difference (d) = 150

We can use the information above to find the explicit rule of the sequence:

a_n=a_1+d(n-1)\\.\quad =1300+150(n-1)\\.\quad =1300+150n-150\\.\quad =1150+150n

We can use the explicit rule to find the 12th term (a₁₂)

a_n=1150+150n\\a_{12}=1150+150(12)\\.\quad =1150+1800\\.\quad =2950

Next, we can input the first and last term of the sequence into the Sum formula:

S_n=\dfrac{a_1+a_n}{2}\times n\\\\S_{12}=\dfrac{a_1+a_{12}}{2}\times 12\\\\.\quad =\dfrac{1300+2950}{2}\times 12\\\\.\quad =\dfrac{4250}{2}\times 12\\\\.\quad =2125\times 12\\\\.\quad =25,500

aalyn [17]

Answer: 56 meters long and 49 meters wide

Convert 350% to a decimal. 350% is 3.5. Each lenth is 3.5x larger than the original pond.

16*(3.5) =56 meters length

14*(3.5) = 49 meters width
