Answer:

  • 76 = 2(x + (3x-2))
  • 28 ft

Step-by-step explanation:

Since x represents the length in feet, and the width is 2 ft shorter than 3 times the length, the width is 3x-2.

The perimeter is twice the sum of length and width, so we can write the equation ...

  76 = 2(x + (3x-2))

  38 = 4x -2 . . . . . divide by 2, simplify

  40 = 4x . . . . . . . .add 2

  10 = x . . . . . . . . . the length of the garden is 10 ft

The width of the garden is ...

  3·10 -2 = 28 . . . feet

The width of the garden is 28 feet.
