<PRE><B>Question 1087638</B>
  the side of a square lot is (5x - 3 ) meters.
 how many meters of fencing materials are needed to enclose the square lot?
 if one square meter of the lot costs pup 15,000, what is the cost of the square lot?
:
perimeter
p = 4(5x-3)
p = 20x - 12 meters required to enclose the square lot
:
Area
A = (5x-3)^2
FOIL (5x-3)(5x-3)
A = 25x^2 - 30x + 9 sq/meters is the area of the lot
Cost
15000(25x^2 - 30x + 9) = the cost of the lot</PRE>
