Hi there!!!
So using this rule:
Area = base * height
20ft * 15ft = 300ft^2
↑ ↑
base height
HOPE IT HELPS U!!!!!!!!!
THE ANSWER IS 300 FT^2

Answer:
B) 
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:

The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:

Finally, we sum both of the areas found to calculate the total area.

So, the answer is option B).
Answer:
see explanation
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given
6(a₁ + 5d) = 13(a₁ + 12d) ← distribute parenthesis on both sides
6a₁ + 30d = 13a₁ + 156d ( subtract 13a₁ from both sides )
- 7a₁ + 30d = 156d ( subtract 30d from both sides )
- 7a₁ = 126d ( divide both sides by - 7 )
a₁ = - 18d
Now
a₁₉ = a₁ + 18d = - 18d + 18d = 0 ← as required
