Step-by-step explanation:
Straight line method assumes a gradual depreciation in value of an asset's useful life.
-It's calculated by dividing the difference between an asset's cost and its expected salvage value by the number of years it is expected to be used.

From our calculation, depreciation is $2,000 per year
Accumulated depreciation=8*2000=$16,000
18% = 18/100 = 0,18
22000/0,18 = 22000/(18/100) = (22000 . 100)/18 = 1100000/9 = 122222,2222...
So $22,000 divided by 18% is equal to $122.222,22
Area = length multiplied by width
35=5x
The other length is 7 yards.
