A company purchased land for $90800 cash. Real estate brokers' commission was $4500 and $6900 was spent for demolishing an old building on the land before construction of a new building could start. Proceeds from salvage of the demolished building was $1000. Under the historical cost principle, the cost of land would be recorded at

 $87,400.00

Explanation:

The cost of land includes all of the cost necessary to bring and make it ready for the intended use. These costs include purchase cost, fees and commission associated with the purchase transaction. Further more, included in the historical cost are the net demolition cost  of old structure to prepare the land for use. Net cost here means cost of demolition less any incidental proceed from the old structure.

However, remember that land is not depreciated because it has an infinite life span.

So using the historical cost principle the cost of the land

= 90,800 + 4,500 + 6,900-1,000

=  $87,400.00

The formula of a perimeter of a square:

We have P = 48. Substitute:

             divide both sides by 4

You can use the Pythagorean theorem, and calculate the length of a diagonal or use the formula of a diagonal of a square:
