Answer:

  • width: 12.8 m
  • length: 13.5 m

Step-by-step explanation:

Let L represent the length of the rectangle. The L-0.7 is the width, and the perimeter is ...

  perimeter = 2×(length +width)

  52.6 = 2(L +(L -0.7))

  54 = 4L . . . . . simpify, add 1.4

  13.5 = L . . . . . divide by 4

  L -0.7 = 13.5 -0.7 = 12.8 . . . . width

The rectangle is 12.8 (width) by 13.5 meters (length).
