x-\ length\\y-\ width\\\\
Perimeter=2x+2y\\\\
175=2x+2y\\
x=2y+6\\\\
175=2(2y+6)+2y\\
175=4y+12+2y\\
175=6y+12\ \ \ |Subtract\ 12\\
163=6y\ \ \ |Divide\ by\ 6\\
y=27,17feet\\\\
x=2*27,17+6=60,34feet\\\\
Length=60,34 \ feet\ and\ width=27,17\ feet.

What is   float rate_of_pay?

  • Floating rates follow the market, a benchmark interest rate, an index, or both.

Is a fixed or floating rate preferable?

  • In a rising rate environment, banks offer fixed rate loans at a higher rate than variable rate loans in order to profit more from the latter when rates rise.
  • Fixed rate loans may have interest rates that are 300–350 basis points higher than floating rate loans.
