Answer:

40 ft by 85 ft

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.
