When calculating the effective rate of interest of a loan, the nominal rate of interest will be equal to the effective rate and the interest is compounded annually in the event that n is equal to 1.
If the duration of the loan, n, is 1 then the nominal rate and the effective rate will always be equal. Moreover, the interest rate charged on the loan is usually stated as an Annual Percentage Rate (APR) of charge compounded annually
easy 230-80 which is 150 so imagine a triangle with base 150 and hight 130-60=70 so times for area 150×70÷2 because it's triangle which is <em>5</em><em>2</em><em>5</em><em>0</em> so plus that with 130x80 for rectangle which is 10400 and add so it's 15650
