Problema Solution
Tata Jose is planning to fence his rectangular backyard for his ducks and geese.He has 26 m of chicken wire to buikd the perimeter.What should the dimensions of he fence be if the length is to be 3 m longer than he width?
Answer provided by our tutors
let
l = the length
w = the width
P = 26 m the perimeter
P = 2(l + w)
2(l + w) = 26 divide both sides by 2
l + w = 13
the length is to be 3 m longer than he width:
l = 3 + w
by solving the system of equations:
l + w = 13
l = 3 + w
we find:
l = 8 m
w = 5 m
