Answer:
138 is the answer
Step-by-step explanation:
In order to find the perimeter, we use this formula
P=2(l+w)
And to find the width, we use this formula
w = P/2 - L = 18/2 - 3 = 6
So the width is 6
3 × 6 = 18
So thats why the perimeter of the top triangle is 18
We do 21 ÷ 3 = 7, 7 = scale factor
To find the perimeter of the bottom triangle, we do
the width of the top rectangle times 7
so 6 × 7 = 48
So the perimeter for the bottom triangle is
P=2(l+w)=2·(48+21)=138
Step-by-step explanation:
P=96
A= 665.11
Not sure about the first part
I think the first part might be 8,.
The total amount owed after three years is $2,837.04.
The formula that can be used to determine the total amount owed after 3 years is:
FV = A(1 + r/m)^nm
- FV = Future value of debt
- A = amount borrowed
- R = interest rate = 12/2 = 6%
- m = number of compounding = 2
- N = number of years = 3
$2000 x (1.06)^6 = $2,837.04

The area of a triangle is 1/2*base*height
So make your equation: 1/2*b*12=42
6*b=42
b=7
So the base is 7 inches long
Hope that helped!
