The amount of yards needed to enclose the field completely is 990 yard
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Let x represent the other side.
640 acre = 1 mile²
25 acre = 0.0390625 mile²
Hence:
0.0390625 = length * width
0.0390625 = 0.25x
x = 0.15625 mile
The amount of mile needed = 2x + 0.25 = 2(0.15625) + 0.25 = 0.5625 mile
1 mile = 1760 yard
0.5625 mile = 990 yard
The amount of yards needed to enclose the field completely is 990 yard
