In this case we have an ARM fixed for 6 years and adjust after the initial first 6 years every 2 years after. The basic idea behind a ARM is that the interest changes periodically, but since our ARM is fixed for 6 years, our going to calculate the monthly payment during the initial period using the formula:

where

is the monthly payment

is the amount

is the interest rate in decimal form

is the number years
First we need to convert our interest rate of 4% to decimal form by dividing it by 100%:

We also know from our question that

and

, so lets replace those values into our formula to find the monthly payment:


We can conclude that the monthly payment during the initial period is $1071.58<span />
63 = 9k
divide by 9 on each side to get k by itself
k = 7
The area of a triangle is base length x height then divide all by 2,
so 12 x 10 /2
=60 ft²
