Answer:
13 feet
Step-by-step explanation:
Define x :
--------------------------------------------
Let the width be x.
Width = x
Length = 2x - 3
--------------------------------------------
Perimeter Formula :
--------------------------------------------
Perimeter = 2 (Length + Width)
--------------------------------------------
FInd Width :
--------------------------------------------
42 = 2 (x + 2x - 3)
42 = 2(3x - 3)
42 = 6x - 6
48 = 6x
6x = 48
x = 8 feet
--------------------------------------------
Find Length :
--------------------------------------------
Length = 2x - 3 = 2(8) - 3 = 13 feet
--------------------------------------------
Answer: The length is 13 feet.
