Answer:

  40 ft by 85 ft

Step-by-step explanation:

The total length of the three "vertical" partitions is ...

  3x = vertical partitions

The total length of the horizontal sides is ...

  2(x +(x +5)) = 4x +10

Then the perimeter is ...

  P = vertical partitions + horizontal sides

  290 = 3x +4x +10

  280 = 7x

  x = 40

  2x+5 = 85

The overall dimensions are 40 ft by 85 ft.
