You have to order fencing for a 25-acre rectangular field one side of the field measures exactly 1/4 mile how many yards of fencing will you need to enclose the entire field

1/4 acre x 100 acres = 25 acres

208.71" = one side of 1 acre squared in feet

2 x 1/4 x 208.17" =      104.355"  (2 x 1/4 acre long ends in feet)

200 x 208.71"      = 41,742.000"  (2 x 100 (acre long sides) x 208.71") 

    41,846.335" divided by 3 = 13,948.785 yards of fencing required

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
