Problema Solution
your dad is designing a new garden for your backyard. he has 20 feet of fencing to go around the garden. he wants the length of the garden to be 2 1/2 feet longer than the width. how long should he make the garden?
Answer provided by our tutors
Let
x = the width
y = the length
Assuming the fencing is rectangular we have:
2x + 2y = 20
y = 5/2 + x (since 2 1/2 = (2*2 + 1)/2 = 5/2)

........
x = 3.75 ft
y = 6.25 ft
The garden should be 6.25 feet long.
