Answer:
30*x + 14850/x
Step-by-step explanation:
Let x be the length of the two opposite sides of the region with material costs of $15 per linear foot.
Let y be the length of the other two sides
Now, we have the following equations
Area of the rectangular región = x * y = 450 ft2
Total cost of fencing = 15*x + 15*x + 15 *y + 18*y
Total cost of fencing = 30*x + 33 *y
We now that area is equal to 450 ft2 = x*y
So y = 450/x
Now we can substitute y in equation for Total cost of fencing and obtain a function that expresses the cost of fencing the region in terms of the length, x
Total cost of fencing = 30*x + 33 *(450/x)
Total cost of fencing = 30*x + 14850/x
