Answer:
$53,734
Step-by-step explanation:
When the "scrap value" of the asset is zero, the depreciation each year can be computed by dividing the replacement cost by the total economic life of the asset. Then the accumulated depreciation is that yearly depreciation multiplied by the effective age of the asset.
Here, we assume the total economic life is the sum of the effective age and the remaining economic life.
So, for example, the accumulated depreciation of the house would be calculated as ...
($131,582)(10 years)/(10 years +30 years) = $131,582(1/4) = $32,895.50
Here, values are shown in the attached spreadsheet rounded to the nearest dollar. The spreadsheet uses full precision values in its calculations.

Depreciation is computed separately for each of the improvements, and the accumulated depreciation is the sum of the individual improvement depreciations. We have used a spreadsheet to do the arithmetic so as to minimize errors and avoid the tedium of repetitive calculations.
The total accrued depreciation is $53,734.
