To explain what is shortest side of the flower bed.
Answer to Problem 5.4.1.4P
12 foot is the shortest length for side of the flower bed.
Explanation of Solution
Given information:
Triangular flower bed
Jocelyn spends between $60 and $70
Fence cost per foot is $1.50
Formula used:
Perimeter of
Wherea, b and c are sides of triangle
Calculation:
First side of triangle=a
Second side of triangle=a
Third side of triangle=a+4 Using formula Perimeter of given triangle=a+a+a+4
ais the shortest side of triangle On solving,
P=3a+4 foot
Cost per foot=1.50
Cost for (3a+4) foot=1.50(3a+4)
Jocelyn spends between $60 and $70 for triangular bed
Then inequality
Dividing by 1.50 all sides of inequality
On solving.
Subtracting 4 all sides of inequality
On solving.
Dividing by 3 all sides of inequality
On solving.
Hence, 12 foot is the shortest length for side of the flower bed.
