Answer:

Length will be 46 ft and width will be 16 ft

Explanation:

Let the width be x.

then the length will be 3x - 2

using the rectangle perimeter formula:

2( length + width )

2(x + 3x-2) = 124

2(4x-2) = 124

8x - 4 = 124

8x = 128

x = 16 ft

Width will be 16 ft and

Length: 3x - 2

           : 3(16)-2

           : 46 ft
  • Width be n
  • Length is 3n-2
