Answer:

The total cost is  $3,504.63

Step-by-step explanation:

Length of fence = 90 feet

Breadth of fence = 175 feet

Height of fence = 6 feet, 6 inches

1 inch = 0.0833333 feet

6 inches = 6*0.0833333 =0.4999998  feet

So, Height of fence = 6 feet + 0.49 feet =6.49 feet ≈ 6.5 feet

Perimeter = [tex]2(Length \times breadth)=2(90 +175) = 530 feet[/tex]

Cost of erecting the fence is $1.25 per linear foot

So, Cost of erecting the fence in 530 feet = [tex]530 \times 1.25 = 662.5[/tex]

Total surface area = [tex]2(length +breadth) Height =530 \times 6.5=3445ft^2[/tex]

The cost of materials is $0.825 per square foot of fence

Cost of material for 3445 sq.feet = [tex]3445 \times 0.825 =2837.7525[/tex]

So, total cost = 2842.125+662.5 = 3504.63

Hence The total cost is  $3,504.63
