you purchase a 50-meter roll of fencing, at a cost of $14.95 per meter, in order to build a dog run that is 340 cm wide and 1380 cm long. After you cut the four pieces of fencing from the roll, how much fencing is left on the roll?

    i believe dog run would be an rectangle.. so the perimeter of rectangle = 2 (l + b) given l = 1380 and b = 340.. So P = 2 (1380 + 340) = 3440 cm.. converting it to meters ... 34.40 m.. so left over = 50 - 34.40 = 15.60 meters..,
