If it's a square and the perimeter totals 28 m, just multiply 28 by $15 to get the cost before taxes.
If it's a square and EACH SIDE is 28 m, then multiply 28 x 4 x $15.
(If I'm wrong, a math teacher will correct me!)

My problem is more with the diagonal being 42. Using a^2 + b^2 = c^2, the sides would not be 28 if the diagonal was 42.
I'll explain it. There is a square in my book. Outside of the squar one of the sides is 28m. Inside the square going across from one corner to the other is 42m
