The area of a triangle is given by the formula
where
b is the length of the base
h is the length of the height
For the 1st triangle here, we have:
b = 6 is the base
h = 8 is the height
So, the area of the triangle is
For the 2nd triangle here, we have:
b = 8 is the base
h = 10 is the height
So, the area of the triangle is

This is a simple dynamical system for whom the the solutions are given as
putting values we get
S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)
= $98005.35
withdrawal of money takes place from one year after last payment
To determine the result we use the present value formula of an annuity date
we need to calculate R so putting the values and solving for R we get
