Problema Solution
susan has 600 feet of fencing to use in making a yard for her new puppy. The yard she has planned has a length that is 75 feet less than twice the width. What are the dimensions of the yard?
Answer provided by our tutors
we will assume that the yard is rectangular.
let
l= the length of the yard
w = the width of the yard
Susan has 600 feet of fencing to use in making a yard for her new puppy
2(l + w) = 600 divide both sides by 2
l + w = 300
the yard she has planned has a length that is 75 feet less than twice the width
l = 2w - 75
by solving the system of equations
l + w = 300
l = 2w - 75
we find
l = 175 ft
w = 125 ft
