A former wants to fence up a rectangular plot of land measuring - by 3.12 metres. Each metre of fencing costs $430.50. Find the perimeter of the plot of land. b) Find the total amount he has to pay for the fencing.
For the perimeter, I used the formula 2(l+w). For the total amount he has to pay, I multiplied the perimeter (15.36) by $430.50 (the total amount for one meter) :)
