find the length of each side 240÷12=20    20 is the other length. 
12•$18=$216   for the street side and 20+20+12=52  is the total length of the other sides 52•$15=$780  is the total cost of other 3 sides  780+216=996
the total cost is $996. Hope this helped

The total cost of fencing is $996.

Cost calculation

Given that David wants to install a fence fence around his garden, and the garden is rectangular and has an area of 240 square feet, and one side of the garden is along the street and is 12 feet long, and for this side of the garden , David will use fencing that costs 18$ per linear foot, while for the other three sides of the garden, David will use fencing that costs 15$ per linear foot, to determine what is the total cost of fencing the following calculation must be made :

  • 12X = 240
  • 240 / 12 = X
  • 20 = X
  • 12 x 18 + 12 x 15 + 20 x 15 + 20 x 15 = Cost
  • 216 + 180 + 300 + 300 = Cost
  • 996 = Cost

Therefore, the total cost of fencing is $996.
