I have a 3 part question that I have the answers for but I am still having issues understanding it. Looking for help with the explanation / steps on how you would get the answer.
1) The width of a rectangular field is 3h yards and it's length is 3 yards longer than the width. The field has a fence around it's perimeter with a gate 4 yards wide.
A) Write an expression for the perimeter of the rectangular field in terms of h, excluding the width of the gate.
(12 h + 2 ) yards
B) It costs $28 per yard to fence the field, excluding the gate. Write an expression that represents the cost of fencing the field.
The cost is 28 (12h + 2 ) dollars
C) If h = 5, find the cost of the fencing, excluding the gate.
The cost is $1,736
