20*70+60*x=50(70+x)

1400+60x=3500+50x

60x-50x=3500-1400

10x=2100

x= 210

x=210 gaL 60 % Antifreeze II

THow much will fencing cost to enclose a field that is 725 feet by 1,021 feet if fencing costs $13.57 per foot? $47,386.44 $23,6
iogann1982 [59]

Answer:

$47,386.44

Step-by-step explanation:

Given;

Dimension of the field = 725 feet by 1,021 feet

Length = 1021 ft

Breadth = 725 ft

Cost per foot = $13.57 per foot

Perimeter of the field = 2 × (length + breadth)

Perimeter = 2 × ( 1021 + 725) = 3492 ft

The cost of fencing the field is;

Cost per feet × perimeter

= $13.57 × 3492

= $47,386.44
